The BL6100 is a unique design, incorporating the need for a narrow stile door section lock not often seen on the market. With a body width of just 45mm, this lock is ideal for areas where conventional locks just won't fit including timber and UPVC doors.This comes with a 325mm long extension plate fitted behind the keypad and inside handle adding an extra 113mm to the length of the unit, effectively making it suitable with 90 and 92mm centred multi-point locks and helping to cover all existing holes on the door.This lock incorporates a single column of 8 buttons, each offering a double button press system, allowing digits to appear twice in the code. The free-turning handle is permanently clutched to provide no handle resistance if the correct code is not entered. This model also features a free passage mode that, when enabled, bypasses the coding chamber to allow access without the need of entering the code all of the time until it is disabled once more. This mode is optional and can be fully disabled should it never be needed.The BL6100 is supplied with no device and is for use with either an existing setup or a third-party latch.Due to the handle rotation, this is ideal for use with multi-point latches. This lock is suitable for internal and sheltered external narrow stile UPVC, aluminium, composite and wooden doors.
