Borg Mechanical Digital Door Lock with Knob Holdback and 28mm Mortice Latch Satin Chrome

Borg BL2202SC Mechanical Digital Lock – Knob Keypad – 28mm Mortice Latch – Holdback – Satin Chrome

The Borg BL2202SC is a fully mechanical digital lock designed specifically for narrow stile doors. Unlike the standard BL2000 series which uses a 60mm backset tubular latch, the BL2202SC uses a 28mm backset mortice latch with a compact 96×26mm faceplate — making it the correct choice for aluminium-framed doors, narrow stile timber doors, and any application where the standard 60mm backset would be too deep for the door stile.

Satin chrome finish, inside paddle handle with holdback, and the traditional Borg tumbler code system (lock removal required to change code). Over 8,000 combinations. Single-sided — the inside handle is always free for immediate egress. Suits doors from 35mm to 54mm thick. No batteries.

28mm Backset – Designed for Narrow Stile Doors
The BL2202SC uses a 28mm backset mortice latch with a 96×26mm faceplate. This compact latch body is specifically designed for aluminium-framed doors, narrow stile timber doors, and any door where the stile is too narrow for a standard 60mm backset latch to be morticed. If your door stile is wide enough to accept a standard 60mm latch, consider the BL2200SC or BL2501SSECP instead.

Inside Handle Always Free – No Code Required to Exit
The inside paddle handle is always free to operate. No code is required to open the door from inside.

Holdback Facility
After entering the code and operating the knob, the holdback can be engaged to keep the latch retracted — allowing free passage without code entry. The holdback device can be permanently removed from the lock if not required.

Code Change Requires Lock Removal
This model uses a tumbler-based code system. To change the PIN, the lock must be removed from the door. Remove the 4 red screws, carefully lift the cover plate (springs attached), hold the C tumbler depressed, then use the supplied tweezers to reposition the red (coded) and blue (uncoded) tumblers. Over 8,000 combinations; code length adjustable 3–7 digits. For on-door code change, see the BL2201SCECP.

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

Designed for light to medium usage areas – internal and sheltered external

Not suitable for high traffic commercial use
For heavy duty: consider the Borg BL7701, Lockwood DX, or Carbine CDL7000.

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

Frequently Asked Questions

Additional Information

Setting Code Before Installation:
The tumbler code can be set on the bench before installation. Set and verify the code before mounting. This avoids removing a fitted lock for the first code change.

Confirming Door Stile Width:
Measure the stile width of your door before ordering. The 28mm backset latch requires a faceplate pocket of 96mm height × 26mm width to be morticed into the door edge. Confirm the stile is wide enough to accommodate this faceplate before purchasing. If the stile is wider than 40mm, a standard 60mm backset latch is likely suitable and may provide a more secure bolt engagement.

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.
