操作指南

1. 1. Confirm the longer drive stroke is what the door needs

   The extended drive structure is for doors where standard vertical drive space is limited or a longer stroke is required; measure the door's pull-in travel before choosing this over the standard 4000-10.

2. 2. Set the stage count and handing on the order

   Single-stage or dual-stage engagement and left- or right-hand orientation are specified at order time — getting handing wrong means the linkage routes the wrong way across the door.

3. 3. Mount through the Ø6.4mm hole or M6×1 thread

   Both fixing options are in the drawing; the threaded connection suits thinner frames, the through hole thicker castings.

4. 4. Match the pin strike to the striker height

   The latch accepts a pin strike up to 9.6 mm; check the striker pin diameter and the engagement depth together.

5. 5. Stay within the 3,300 N ultimate load

   Ultimate load is 3,300 N for both the zinc-plated and stainless builds; size the door gasket compression so the latch is not working at its ceiling.
