What is a hotel knob lock?

Knob Locks

A knob lock combines the handle set and the mortise lock in one product: two holes in the door and the set fits straight on. It is used on hotel, office and interior doors. The catalogue holds 7 models.

One-piece sets and functions

The mechanism sits inside the knob, so there is no need to buy a mortise lock and handle set separately. Fitting takes one round hole through the leaf and one latch hole in the edge, which saves considerable time in refurbishment and volume installation.

The functions are the same as any other lock: passage works on the latch alone, bathroom-WC adds an inside thumbturn, and the entrance function locks with a key. Hotel versions can be set up on a master key plan.
