What the AI looks for in Door Closers
- Closer size
- Match closer size (1 to 6) to door width and weight; adjustable-size closers cover several sizes An undersized closer won't latch the door, and an oversized one makes it hard to open.
- Arm mounting
- Regular arm on the pull side, parallel arm on the push side, or top-jamb mount; confirm the closer supports the one you need The arm type determines which side of the door the closer mounts on and how much force it delivers.
- Opening force
- Accessible interior doors are generally limited to 5 lbf opening force Accessibility codes cap how hard a door can be to open.
- Valves
- Separate sweep, latch and backcheck adjustment Backcheck keeps wind from slamming the door into the wall, and the latch valve sets reliable closing.
- Handing
- Non-handed or field-reversible This avoids ordering the wrong unit for left- or right-hand doors.
Brands that matter
- LCN: Commercial benchmark for surface closers.
- Norton: Established commercial closer maker.
- Dormakaba: Commercial closers and concealed options.
- Wright Products: Pneumatic storm and screen door closers.
What to avoid
- Residential pneumatic tube closers on full-weight exterior doors
- Closers without backcheck on doors exposed to wind
- Leaking hydraulic closers; once they leak they need to be replaced
Questions
Regular arm or parallel arm?
A regular arm mounts on the pull side and projects out from the frame. A parallel arm mounts on the push side and folds flat against the door, which better resists abuse.
