Borg Mechanical-Digital 2605 Marine Knob Rim Mount DeadBolt

Borg BL2605 MG Pro Mechanical Digital Knob Lock – Rim Mount Deadbolt – Marine Grade Pro – Matt Black

The Borg BL2605 MG Pro is a fully mechanical digital knob lock fitted with a rim-mounted surface deadbolt instead of a standard tubular latch. This makes it specifically suited to external doors and gates where the door section is too thin, too narrow, or otherwise unsuitable for a conventional tubular latch installation. The lock 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 exposure.

Operation is deadbolt-based: entering the correct PIN code on the keypad withdraws the bolt, allowing the door to be opened. Locking from inside is done by turning the inner thumb knob to throw the bolt. Unlike tubular latch products, the deadbolt does not automatically engage when the door closes – the bolt must be manually thrown from inside each time to secure the door. The lock is fully mechanical, requires no batteries, and has no wiring of any kind.

The BL2605 MG Pro uses the traditional Borg tumbler-based code system. Code changes require removing the lock from the door. For an on-door code change version, see the BL2606 MG Pro ECP, which uses a hook bolt designed for sliding doors.

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

Rim-Mount Deadbolt – Surface Mounted, No Mortice Required
The BL2605 MG Pro uses a surface-mounted rim deadbolt instead of a tubular latch. The deadbolt body mounts to the inside face of the door – no mortice boring into the door edge is required. This makes it the correct choice for thin-section aluminium gates, glass-framed doors, or any application where drilling a standard 25mm barrel hole through the door edge is not possible or practical.

Important – Deadbolt Does Not Auto-Lock on Door Closing
Unlike tubular latch models, the rim deadbolt does not automatically engage when the door closes. To lock the door from inside, the inner thumb knob must be manually turned to throw the bolt. Confirm this operation suits your application before purchasing.

Marine Grade Pro 2 – Saltwater and UV Resistant Construction
The BL2605 MG Pro uses Borg's MG Pro 2 marine grade external coating, providing 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.

Fully Mechanical – No Batteries Required
The BL2605 MG Pro is entirely mechanical. No power source, no wiring, and no battery maintenance at any point in the product's lifetime.

Designed for light to medium usage areas

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 BL2605 MG Pro accepts one active PIN code at a time.

Code Change Requires Lock Removal
The BL2605 MG Pro uses a tumbler-based code system. To change the PIN, the lock must be removed from the door, the internal cover plate removed, and the red coded and blue uncoded tumblers rearranged using the supplied tweezers. For on-door code change, the BL2606 MG Pro ECP (sliding door hook bolt with Easicode Pro) is the related ECP variant.

BL2605 vs BL2606 – Which Model is Right for Your Application?

Both models share the MG Pro 2 marine grade coating and 1,000 hour salt spray rating. Choose BL2605 for hinged doors requiring a rim deadbolt; choose BL2606 for sliding doors or gates where a hook bolt suits the frame.

Frequently Asked Questions

Additional Information

Handing the Lock – Two Separate Operations:
Unlike tubular latch models where only the latch needs to be reversed, the BL2605 requires both the keypad and the rim deadbolt body to be individually handed. The keypad uses a handing pin and disc mechanism; the rim deadbolt is reversed by removing the cover plate and flipping the bolt body. Both must be set to the same hand. Test the knob rotates freely in the correct direction after reversing – the knob should rotate freely in one direction and be solid in the other before the code is entered.

Strike Plate Options – Morticed and Surface Mount:
The BL2605 includes both a morticed lock keep and a surface-mounted strike, giving installers flexibility depending on the gate post or door frame construction. On thin-section aluminium frames where morticing is not possible, the surface-mounted strike can be used. Confirm which strike configuration suits your frame before installation.

Maintenance – BL2605 Specific Instructions:
The Borg BL2605 series maintenance instructions specify the following schedule: Weekly – clean the surface of the lock with marine grade chrome polishing liquid and spray the exposed bolt and deadbolt components with WD-40 or equivalent. Annually – remove the lock, spray the inside through the tumbler holes with WD-40, spray all fixings and the deadbolt, then test all buttons and the knob for smooth operation. Note: the BL2605 series instructions specify WD-40 (unlike the general Borg servicing guide which recommends silicon-based lubricant) – follow the product-specific instructions.

Code Change – Do It on the Bench First:
The factory preset code is printed on the Code Card included in the box. Change the code before fitting the lock – it is significantly easier to work with the lock face-down on a flat surface than after installation. Once the lock is fitted to the gate or door, any code change requires full removal. Set and verify the new code at least three to four times on the bench before mounting.

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.
