Borg Locks

The BL2521 falls under our Codestar range of mechanical push button locks. Manufactured to the highest standard with premium components, these are typically made from stainless steel to guarantee longevity. Instead of the standard internal handle, this lock has back to back keypads, meaning a code is required to both enter and exit.

With both keypads being cycle tested to 100,000 cycles to show their durability, this lock represents the medium tier of small, mechanical keypad locks. Both keypads come with over 8,000 potential combinations that can be separate to each other due to individual coding chambers.

This lock comes with an anti-thrust tubular latch that comes in three different sises: the 50mm, the 60mm and 70mm backsets.

The BL2521 is suited for wooden and composite doors both internally and sheltered external applications.
