Modular Design and Installation

KFV locks have evolved, with many older models now discontinued. The new modular design allows for easier replacements without needing to change routing positions. When replacing old locks, adjustments may be necessary for keeps or hook boxes, especially if there’s limited clearance.

• Overall Height: 210mm
• Bolt Throws: 21mm

New KFV gearboxes are secured to the faceplate with screws, while older models used 1/8" rivets, which can aid in identification.

Lock Variants

KFV locks are available in lift lever or key wind variants. Note that these two types are not interchangeable.

Measuring Backset

When measuring the backset, remember to account for a 2-3mm allowance for the faceplate. For instance, a 35mm backset gearbox will measure 32mm when detached from the strip.

Deadbolt Features

KFV deadbolts are characterized by a chamfered center, which aids in connecting to the keep. The distinctive shape, with raised parts at the top and bottom, assists in lock identification.

Roller Functionality

Rollers serve to compress the door against the frame, minimizing dust and water ingress. While they do not significantly enhance security, they help prevent door warping by providing support along the full height of the door, contingent on proper engagement with their keeps. Rollers are typically adjustable by 1mm for optimal weather sealing.
