Inset locks have many uses, and have long since moved on from the sports halls they were originally designed for. Nowadays, these fittings can be found in many large buildings: pass doors in large sliding gates, fire compartment doors, sliding doors, in multi-purpose halls and concert halls. They’re also used wherever space is at a premium, in the side doors on an emergency exit route, and for many other applications.

Extended passage width / clearance width
with flush-mounted HEUSSER-Inset Locks
The effective passage width of doors in escape routes, also called clearance width, is an important factor in the suitability of escape routes. For example, one standard requires a clearance width of at least 875 mm for single-leaf doors for up to a number of 5 persons. Compared to conventional lever handles, flush-mounted HEUSSER-Inset Locks create valuable space in the passage width and also help to comply with the relevant standards for escape and rescue routes.
The following illustrations show the advantage of using flush-mounted HEUSSER-Inset Locks:
Marking of the active leaf
by colour-coded HEUSSER-Handles
The handles for the HEUSSER-Inset Locks are optionally available in the signal colors red and green. These are used by the user for simple and clear identification of the door leaf to be used normally (active leaf).
