操作指南

1. 1. Use the top drive where headroom above the frame is tight

   The compact top drive design is made for installations where space above the door frame is limited; confirm the linkage routing clears the frame top before final mounting.

2. 2. Pick the stage count for the door travel

   Single-stage and dual-stage configurations cover short and longer pull-in distances; dual-stage gives more clamping travel on heavily gasketed light doors.

3. 3. Fix via Ø6.4mm through hole or M6×1 thread

   The two fixing options cover different frame gauges; use the threaded bosses where the frame is too thin to drill a clean through hole.

4. 4. Accept the no-cushion trade-off on the right doors

   This model is built without a cushioning device for a simpler, more robust structure — fine on lightweight equipment doors, but expect audible latching on doors that slam shut.

5. 5. Hold gasket compression inside the 3,300 N rating

   The latch carries ultimate loads up to 3,300 N; on dust-proof sealing applications, verify the gasket reaction force stays comfortably below that figure.
