The CL100 is a light duty surface bolt. The bolt slides on the inside surface of the door to lock or unlock. The bolt is moved manually by means of the outside knob after the code is entered, and freely by the inside knob at all times.
This entry level mechanical push button lock is for light duty entry control, for inner office doors, storage rooms or cupboards in commercial premises, sheds, garage-to-house doors or cupboards at home.
Delivered with random, unrecorded codes, simply change the code by following the clear instructions provided. Installation couldn't be simpler either - just drill one hole for the spindle, two holes for the fixing bolts.
