  Trilock Series Gainsborough guarantee
 

3 in 1 Operation | 3 functions in the one lockset.
 
  • Lockset with safety. Depressing the button on the inside of the door engages the Trilock lockset mode. This locks the door from the outside; however, it is safe to exit without a key in an emergency by simply turning the inside knob or lever.
  • Deadbolt security. Trilock houses a key-operated double cylinder deadbolt, with a sturdy 20mm throw. (Single cylinder version features inside turnbutton.)
  • Passage set convenience. When Trilock is unlocked and unsnibbed, it operates as a standard passage set, allowing free access in or out of the home.

Trilock models available
Double Cylinder -
Key from either side will lock or unlock deadbolt

Single Cylinder -
Key from outside or turn-button from inside will lock or unlock deadbolt. Note: specify left or right-handed when ordering.

Dummy Sets -
A non-operational handle set for the fixed side of a double door.
