Dimensions and installation
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.
