Dimensions
What you can adjust
- Two-stage closing speed. The main swing and the final latch are adjusted separately — the factory quotes 180°–15° for the sweep and 15°–0° for the latch. In practice that means you can slow the door down without leaving it too weak to push the latch home.
- Adjustable closing power. Closing force is set on the unit itself rather than fixed at the factory, so one model covers a range of door sizes and can be tuned after it is hung.
- Backcheck (BC). Resists the door near the end of its opening swing, so wind or a hard shove does not throw the leaf into the wall behind it.
- Delayed action (DA). Holds the door open for a moment before it starts to close — useful where people carry things through, or where a wheelchair needs the time.
