Borg Mechanical-Digital 2621 Marine Knob/Knob - Back-to-Back Keypads - Black

Borg BL2621 MG Pro ECP Mechanical Digital Knob/Knob Lock – Back-to-Back Keypads – Marine Grade Pro – Easicode Pro – Black

The Borg BL2621 MG Pro ECP is a fully mechanical digital lock fitted with keypads on both sides of the door – the knob/knob back-to-back configuration. Entering the correct PIN code is required to open the door from either side, making it the correct choice for areas requiring controlled access in both directions. It is part of the Marine Grade Pro series, finished in MG Pro 2 black marine grade coating and tested to 1,000 hours of continuous salt spray.

The BL2621 MG Pro ECP uses the Easicode Pro (ECP) system for on-door code change without lock removal. An anti-thrust deadlatch pin ensures the door automatically secures when closed. The lock is fully mechanical, requires no batteries, and is cycle tested to 100,000+ operations – double the cycle rating of the single-sided BL2601 model.

For a single-sided version (keypad outside, free lever inside), see the BL2601 MG Pro ECP.

Usually same day if ordered before 11am AEST (excluding weekends and Qld public holidays)

Back-to-Back Keypads – Keypad on Both Sides
The BL2621 MG Pro ECP has a full keypad unit on both the outside and inside of the door. Both keypads share the same code. This configuration provides controlled access in both directions and is designed for applications where entry and exit must both be code-controlled.

Code Required to Exit – No Free Egress from Inside
Unlike single-sided models where the inside lever is always free to turn, the BL2621's inside keypad requires the correct PIN to be entered before the inside knob will operate. Occupants cannot exit without knowing the code. Confirm this controlled-exit operation suits your application and complies with any applicable fire egress or building regulations before purchasing.

Marine Grade Pro 2 – Saltwater and UV Resistant Construction
MG Pro 2 marine grade external coating provides increased protection against saltwater corrosion and UV degradation. Suitable for pool gates, waterfront properties, marina facilities, and coastal environments where standard finishes degrade prematurely.

1,000 Hour Salt Spray Tested – Corrosion Resistance Warranted for 12 Months
Tested to 1,000 continuous hours of salt spray exposure. Borg warrants corrosion resistance for 12 months from date of sale under specified conditions.

Easicode Pro – On-Door Code Change
The PIN code can be changed on the door using the included code change key – no lock removal required. A code change disabling plug is included to prevent unauthorised code changes once set.

Fully Mechanical – No Batteries Required
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point in the product's lifetime.

Designed for external medium duty doors and gates

Not suitable for high traffic commercial use
For heavy duty: consider the Lockwood DX, Borg 7701, or Carbine CDL7000 Series.

Single PIN Code Only
The BL2621 MG Pro ECP accepts one active PIN code at a time. The same code operates both the outside and inside keypads simultaneously.

Frequently Asked Questions

Additional Information

Fire Egress Compliance:
The BL2621's back-to-back configuration means occupants must enter the PIN to exit. In most Australian buildings, doors on exit paths are required to be operable without a key or code in an emergency under the National Construction Code (NCC). Confirm with your building certifier or fire safety consultant that this lock's operation is compliant for your specific application and occupancy classification before specifying it on any door that may be part of an exit path.

100,000+ Cycle Rating:
The BL2621 is cycle tested to 100,000+ operations, compared to 50,000+ for the single-sided BL2601. This higher rating reflects the additional mechanical demand of operating both keypads and makes the BL2621 appropriate for medium-duty doors that see more frequent use. For very high traffic applications, still consider a purpose-rated heavy duty product.

Marine Grade Maintenance:
Monthly: clean both keypad surfaces with a light spray of silicon-based lubricant (such as GT85); remove excess with a soft cloth. Do not use WD-40 or oil-based lubricants on this model – follow the general Borg servicing guide which specifies silicon-based products. Annually: remove the lock, spray internally through the button holes on both units, and test all buttons and both knobs. Refer to the Borg Servicing Guide PDF for full instructions.

Gate Frame Latch Compatibility:
If fitting to a narrow aluminium gate frame (50mm x 50mm or similar), the 60mm backset tubular latch included in the box will not align correctly with the gate frame. An extended gate latch (BLS272000 – left and right hand options) is required. Add the correct gate latch to your cart before ordering to avoid delays at install.

Borg Locks Warranty – 12 Months (Australia)
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.
