Borg Mechanical-Digital 3430 Gate Lock Back-to-Back Lever Handle

Borg BL3430 Mechanical Digital Gate Lock – Back-to-Back Keypads – Marine Grade – Black

The Borg BL3430 is a fully mechanical marine grade digital gate lock with keypads on both sides of the gate – the back-to-back (BTB) configuration. The correct PIN is required to operate the gate from either side. Both keypads share the same factory preset code, but each can be independently recoded to different combinations if required.

Like all products in the BL3400 series, the BL3430 uses a forend fixing system clamping onto the gate post – no mortice cutting required. It suits gate profiles from 30mm to 60mm square on standard telescopic fixings. The lock is fully mechanical, requires no batteries, and features an anti-climb housing.

Code change uses the traditional Borg tumbler system (lock removal required). For on-gate code change, see the BL3430MGPROECP.

Designed for Metal Box-Section Gate Frames – Not a Door Lock
The BL3430GATE is a purpose-built gate lock. It uses a forend fixing system that clamps directly onto the gate post – no mortice cutting or door-edge drilling required. Designed for square aluminium or steel gate posts from 30–60mm. For profiles wider than 60mm, an optional XL latchbolt extension is available separately.

Marine Grade – 1,000 Hour Salt Spray Tested
Marine grade quality keypads tested to 1,000 hours of salt water exposure. Suitable for coastal, beachside, and outdoor gate installations.

1 Year Guarantee Against Faulty Materials and Workmanship

Code Change Requires Lock Removal
This model uses a tumbler-based code system. To change the PIN, the lock must be removed from the gate. The keypad cover plate is removed, and red coded / blue uncoded tumblers are rearranged using the supplied tweezers. For on-gate code change, see the BL3400MGPROECP (single-sided) or BL3430MGPROECP (back-to-back).

Back-to-Back Keypads – Code Required Both Sides
This model has a full keypad unit on both the outside and inside of the gate. The same PIN code operates both keypads. Entering the code is required to enter and exit — there is no free egress from inside.

Fully Mechanical – No Batteries Required
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point.

Single PIN Code Only
Accepts one active PIN code at a time.

Code Required to Exit – No Free Egress from Inside
Unlike single-sided models, the inside keypad requires the correct PIN before the lever operates. Confirm this suits your application and complies with any applicable fire egress or building regulations before purchasing.
