Description of operation
From the outside the latch – and if double locked, also the dead bolt – can be retracted with the key (latch lever action). A door can be opened from the outside with the key only as the knob is fixed ( turn of the knob is not necessary / possible ). Double locking from the outside is always possible with the key.
From the inside the door – even if double locked – can be opened by engaging the handle only (Anti-Panic-Release- Function). From the inside the door can always be double locked with the key (or with a cylinder thumb-turn).
The Anti-Panic-Release- Function guarantees easy access from the inside in case of emergency. The Latch Lever facilitates retraction of both latch and dead bolt when the key is used from the outside.

What are the genral handings of a door?
The hand of door for mortise locks is defined as:
if the door is closed and the hinges are visible on the right/left, then the door is right/left hand. The door is therefore hinged on the right/left and according by definition of DIN right/left.
Or: if you grasp the handle with your right hand and latch and deadbolt show to the left, then it is right hand. If you grasp the handle with your left hand latch and deadbolt show to the right, it is a left hand.
The hand of door for rim locks is defined as:
if the door is closed and the hinges are visible on the right/left, then the door is right /left hand. The door is therefore hinged on the right/left and according to the definition DIN “right/left".
In addition to the designation “left” and “right”, it is to be indicated whether the locks are intended for inward or outward opening doors.
Sliding door mortises
The hand of door for sliding door mortises is the same for right and left. Sliding rim door locks different for left and right doors.
When ordering, always indicate “left” or “right”.
What are the essential components of a lock?
The lock latch keeps the door shut. In order to open the door, it must be retracted. There are several designs for the latch:
anti-vibration or three-piece latch
POM-latch for strike dampening
The deadbolt regulates the access rights through the turning motion of the cylinder by key. The deadbolt is being driven out or retracted through the turning motion.
The faceplate is the visible part of the lock case. The faceplate, the latch and the deadbolt are the only visible parts of a mortise
The handle hub takes the square spindle of the handle in order to retract the latch inside the lock through the turning motion of the same. This process allows the opening of the door.
The shipbuilding norm specifies a 9mm square with a 2° incline. Schwepper supplies also with 8mm square, special contour or 0° incline on request.
The WC hub takes the square spindle of the olive or thumb turn, that retracts or drives out the deadbolt from the inside - analogue to the turning motion of the cylinder.
The shipbuilding norm specifies a 7mm square. Schwepper supplies also with 8mm square on request.
What are the essential dimensions of a lock?
The backset is the distance from the front edge of the faceplate to the center of the cylinder hole respectively handle hub square.
The rear backset behind the center line remains always 27mm.
The distancing is the dimension from the center of the handel hub and the center of the hole for profile cylinder / privacy (WC) / key.
The industry standard in shipbuilding is 75mm.
The latch protrudes according to the industrial DIN standard in shibuilding 14mm.
Other technical standards for latch protrusion are:
16 mm according to DOT (Department of Transportation)
19 mm according to USCG (US Coast Guard)
