Borg BL2506 ECP Mechanical Digital Knob Lock - Sliding Door Hook Bolt - Easicode Pro - Satin Chrome
At A Glance
(Not Available)
The Borg BL2506 ECP is a fully mechanical digital knob lock fitted with a hook bolt specifically designed for sliding doors. The hook bolt engages with the door frame strike automatically when the sliding door closes - no manual bolt throw required. To open from outside, the correct PIN code is entered; the inside knob is always free to turn for immediate egress at any time. Finished in satin chrome. Fully mechanical - no batteries.
The BL2506 ECP uses Easicode Pro (ECP) on-door code change, allowing the PIN to be changed while the lock is fitted using the included code change key - no lock removal required. A code change disabling plug is also included to prevent unauthorised code changes. Suits doors from 35mm to 54mm thick (up to 85mm with XL kit).
For a marine grade black version with 1,000hr salt spray rating for coastal and outdoor sliding door applications, see the BL2606 MG Pro ECP.
Usually same day if ordered before 11am AEST (excluding weekends and Qld public holidays).
The BL2506 uses a hook bolt instead of a tubular latch or rim deadbolt. The hook is shaped to engage correctly with the sliding door frame strike as the door moves into the closed position. It is not suitable for hinged doors. Two strikes are included - a universal sliding door strike and a flat strike - to suit a range of aluminium and timber sliding door frame profiles.
The hook bolt engages with the strike plate automatically as the sliding door is pulled closed. No code entry or manual bolt throw is needed to secure the door. To open from outside, enter the code; the inside knob is always free to turn for egress at any time.
The PIN code can be changed while the lock is fitted using the included code change key. No lock removal, no tools, no special knowledge required. A code change disabling plug is included to prevent unauthorised changes once the code has been set by an administrator. For the full step-by-step procedure see Changing Codes on Mechanical Digital Locks - Borg ECP.
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point in the product's lifetime. The lock operates identically on day one and year ten. See What Is a Mechanical Digital Lock? for how the coding chamber works.
The BL2506 ECP is rated for light to medium duty applications on internal and sheltered sliding doors. Cycle tested to 50,000+ operations.
For external coastal or marine applications see the BL2606 MG Pro ECP (1,000hr salt spray, MG Pro 2 black). For high-cycle commercial applications consider the Lockwood DX Mortice or Borg BL7701 Heavy Duty.
The BL2506 ECP accepts one active PIN code at a time. Multiple codes cannot be stored simultaneously. The code can be changed on the door using Easicode Pro without removing the lock.

BL2506 vs BL2606 - Which Model Suits Your Application?
Both models use a hook bolt for sliding doors and feature Easicode Pro on-door code change. Choose BL2506SCECP for internal or sheltered satin chrome applications; choose BL2606MGPROECP for any external, coastal, or marine environment where the MG Pro 2 coating and 1,000hr salt spray rating matter.

Frequently Asked Questions
Sliding doors move laterally rather than swinging, so a tubular spring latch or rim deadbolt cannot engage correctly with a sliding frame. The hook bolt is shaped to hook into the strike as the door slides into the closed position, providing secure engagement suited to lateral door movement. For the full comparison see Latch vs Bolt Mechanical Digital Locks.
Yes. When the sliding door is pulled closed, the hook bolt engages with the strike automatically. No code entry or manual bolt throw is needed to secure the door. To open from outside, enter the PIN code. The inside knob is always free to turn so you can open from inside without any code entry.
With the door in the open position, enter the current code. Insert the included code change key into the hole in the * (star) button and hold it down. Press C to clear the existing code. Enter the new code. Release the code change key. Press C to confirm. Test the new code at least five times before closing the door. If a mistake is made during entry, press C to cancel and start again. Full procedure at Changing Codes - ECP Steps.
Two strikes are included. The universal strike suits most standard aluminium sliding door frame profiles. The flat strike is for timber-framed or flat-profile frame applications. Trial-fit before final fixing and check that the hook bolt enters the strike opening cleanly on every close cycle. A misaligned strike will cause engagement failure or premature wear. For gate stile sizing see Gate Post - Measure the Stile.
Both use a hook bolt for sliding doors and have Easicode Pro on-door code change. The BL2506SCECP is finished in satin chrome with a rain-resistant standard coating - it suits internal or sheltered external sliding doors. The BL2606 MG Pro ECP is finished in MG Pro 2 black marine grade coating with 316 stainless steel internals, tested to 1,000 hours salt spray, and is suitable for external, coastal, poolside, and marine environments. If the installation is coastal or directly weathered, the BL2606 is the correct product.
Additional Information
The hook bolt must engage cleanly and squarely with the strike on every close cycle. Trial-fit the chosen strike before final fixing and check that the hook bolt enters the opening without binding or requiring force. A misaligned strike will cause engagement failure or accelerated wear. The universal strike suits the majority of standard aluminium sliding door frame profiles used in Australian residential construction.
The BL2506SCECP suits doors from 35mm to 54mm thick with the standard 120mm flat bladed sprung spindle supplied. For doors up to 85mm thick, an XL extension kit (Part S227, available separately) extends the spindle to bridge the thicker section. Confirm door thickness before ordering.
The BL2000/BL2500 ECP series uses the * (star) button to initiate code change. Always test the new code at least five times before closing the door. Once set, insert the disabling plug to prevent unauthorised changes. Download the ECP Instructions V4 PDF for the full illustrated procedure.
The BL2506SCECP carries a rain-resistant standard satin chrome coating. It is not rated for direct coastal salt air, poolside, or marine exposure. For any outdoor, beachside, waterfront, or coastal sliding door application, specify the BL2606 MG Pro ECP (MG Pro 2 marine grade, 1,000hr salt spray tested). See MG Pro and ECP Explained - Salt Spray for the rating comparison.
All Borg locks are warranted against mechanical defects in materials and workmanship under normal use and service for a minimum of 12 months from date of sale. The warranty does not cover damage arising from misuse, vandalism, or improper installation. The lock must not be dismantled - doing so will invalidate the warranty.
Borg BL2506 ECP - FAQ, Setup and Owner's Guide
Full detail on the BL2506 ECP satin chrome sliding door hook bolt lock. For context see What Is a Mechanical Digital Lock? and Buyer's Guide Chapter 16 - Mechanical Digital Locks.
The Hook Bolt and How It Works
A hook bolt is a bolt shaped like a fishhook. As the sliding door moves laterally into the closed position, the hook travels through the strike opening and the door's own momentum rotates the hook into engagement. A tubular spring latch or rim deadbolt cannot engage correctly with a sliding frame - they require a linear push or manual throw. For the full comparison see Latch vs Bolt Mechanical Digital Locks.
Yes. The hook engages with the strike plate on every close cycle without any code entry or manual action. The door is secured as soon as it reaches the closed position. Opening from outside always requires the PIN code. Opening from inside requires only turning the inside knob - no code, no key.
No. The hook bolt always engages on closing. There is no holdback or passage mode on the BL2506. If the sliding door needs to be held open for extended periods, a separate door stop or retainer will be needed alongside this lock. See Passage Mode vs Holdback Mode for products that carry this function.
Trial-fit both before committing. The universal strike suits most standard extruded aluminium sliding door frame profiles used in Australian residential construction. The flat strike suits timber frames or flat-profile facings. The hook bolt must travel cleanly into the strike opening without binding. Too tight and the door will not close properly; too loose and the bolt will rattle. If the door sags over time and the strike misaligns, the lock will appear to fail - this is a frame alignment issue, not a lock fault. For stile sizing guidance see Gate Post - Measure the Stile.
Yes. Both the keypad handing and the hook bolt handing are reversible on site. The keypad handing is changed by removing two screws from the back cover plate, repositioning the handing pin and disc, and refitting. The hook bolt handing is changed by removing four screws, flipping the deadbolt horizontally, and refitting. Full instructions are in the ECP Instructions V4 PDF.
Code Change and PIN Management
With the door open: enter the current code, insert the code change key into the * button hole and hold it, press C to clear the existing code, enter the new code, release the code change key, press C to set the new code. Test the new code five times before closing the door. For the full illustrated procedure see Changing Codes - Borg ECP and download the ECP Instructions V4 PDF.
Yes. Borg specifies the code change must be performed with the door in the open position. The code can be changed with the lock fitted to the door or off the door - but not while the door is closed and latched. Always test the new code at least five times with the door open before closing it.
Over 4,000 user-defined combinations from the 12 coded buttons. The code is set by the user on installation - there is no factory-set default code. This figure is consistent across all BL2000/BL2500 ECP series documents.
No. The BL2506 ECP stores one active PIN code at a time. If you need per-user code management, this lock is not the right product. For a product with back-to-back access in marine grade see the BL2621 MG Pro ECP (back-to-back, 60mm latch).
Once inserted into the code change hole in the * button, it physically blocks the code change procedure from being initiated on the door. Only someone who removes the plug first can change the code - useful in managed or shared-access environments where you want administrator-only code control. The plug is removable without tools when access reinstatement is needed.
Finish and Environment Suitability
Not for coastal or marine environments. The satin chrome finish carries a rain-resistant standard coating but is not tested or rated for direct salt air, poolside, or sustained weathering. For any outdoor, beachside, waterfront, or coastal sliding door, specify the BL2606 MG Pro ECP (MG Pro 2 coating, 1,000hr salt spray rated, 316 SS internals). The salt spray rating comparison is covered in full at MG Pro and ECP Explained - Salt Spray.
The BL2506SCECP uses standard satin chrome plating - rain resistant but not tested for salt spray. The BL2606 MG Pro ECP uses Borg's MG Pro 2 black polymer/epoxy coating - a purpose-built marine grade external coating tested to 1,000 continuous hours of salt spray exposure, with 316 stainless steel internals and a specifically corrosion-resistant coding chamber. Both use the same hook bolt mechanism and Easicode Pro code change. The coating is the only meaningful difference between the two models for the same sliding door application.
Installation and Door Suitability
35mm to 54mm with the standard 120mm flat bladed sprung spindle supplied. Doors up to 85mm thick can be accommodated with the XL extension kit (Part S227, ordered separately). Most standard Australian aluminium sliding door and gate sections fall within the 35-54mm standard range. Measure the door or frame section before ordering.
No. The hook bolt is designed for lateral sliding movement and will not function correctly on a hinged door or gate. For a hinged door application in the same Borg ECP range, see the BL2605 MG Pro ECP (rim-fixed deadbolt, hinged doors and gates, marine grade). For a back-to-back gate lock see the BL3430 MG Pro ECP.
Only the inside-handle side of the spindle may be cut if it is too long for the door thickness. The keypad side must never be cut - the full bladed length is needed to seat correctly in the cylinder and ensure smooth operation. This is stated explicitly in the ECP Instructions V4 and applies to all BL2000/BL2500 ECP models.
Mechanical Digital Identity - No Batteries, No App
The BL2506 requires no power at all. There are no batteries to go flat, no firmware to update, no app to configure, no connectivity to lose. On a sliding door that is accessed multiple times daily, the absence of electronics means one fewer failure point. See What Is a Mechanical Digital Lock - Why Choose One?.
Single PIN code only - no per-user codes or access schedules. No key override - if you need mechanical key backup, look at the Lockwood DX range. No audit trail, no remote management, no notifications. The hook bolt suits sliding doors only - not hinged doors. Not rated for coastal or marine environments. See Mechanical Digital Locks - Limitations.
