FAQ – Handings | essential components | essential dimensions of a lock

What are the general handings of a door?

Answer: Mortises

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.



Rim locks

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?

Answer:

Latch

The lock latch keeps the door shut. In order to open the door, it must be retracted.
Type of latch design Illustration
single latch
anti-vibration or three-piece latch
rolling latch adjustable
POM-latch for strike dampening


Deadbolt

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.
Faceplate

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.
Handle hub

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.
WC-/privacy hub

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?

Answer:
