Buyer Questions This Page Should Answer
What is a backset and CTC on a door lock?
Backset is the distance from the edge of the door to the centre of the lock spindle/cylinder (55 mm or 60 mm in this range). CTC (centre to centre) is the distance between the spindle centre and the keyhole/handle centre (72 mm, 78 mm, or 85 mm in this range). Both measurements must match your existing door prep or cutout.
What does DIN Left/Right mean?
DIN Left/Right indicates the lock is configured for a specific door swing direction. Hettich's HBS 31 locks in this category are available in DIN Left/Right configurations to fit standard door orientations.
What door types are these locks compatible with?
The filterable door types are Steel/Wooden and Steel/Wooden/Profile Framed, covering common residential and light commercial door constructions.
What's the difference between the Bathroom Lock, Roller Latch Lock, and Security Lock?
- Bathroom Lock (FBL): designed for bathroom door privacy/latching applications
- Roller Latch Lock (FRL): uses a roller latch mechanism for door closure
- Security Lock (SL): the dedicated security-focused lock in the range
Is a PZ escutcheon required separately?
Yes. The Hettich Round PZ Escutcheon is listed as a separate accessory (trim/cover plate) and is not automatically bundled with the lock sets.
How to Choose the Right Lock
1. Measure your door's existing backset (55 mm or 60 mm) and CTC (72 mm, 78 mm, or 85 mm).
2. Confirm your door type: steel/wooden or steel/wooden/profile-framed.
3. Match DIN Left/Right orientation to your door's swing direction.
4. Select Bathroom Lock, Roller Latch Lock, or Security Lock based on the application (privacy vs. security vs. latch-only).
5. Add a PZ escutcheon if your installation needs a separate trim plate.
