Flush-mounted design, tool-less adjustment and precise compression – the new stainless steel compression latches
01 Requirements
Rail transport is subject to peak requirements in design, function and material. Our challenge was to combine the advantages of a flush-mounted quarter turn with those of a compression latch while ensuring easy, tool-less adjustment of the cam.
Our solution: The flush-mounted compression latches made of stainless steel with different housing lengths with a fixed cam or tool-less adjustable with a knurled wheel. All versions provide a precise compression combined with a flat surface.

03 Product advantages
7-086 | Flush-mounted compression latch
- Flush-mounted design: does not extend outward and therefore avoids the risk of getting caught for increased safety, for example in escape routes
- Closing position visible: marks on housing and inserts for visualization of the exact closing position
- Compression 6 mm: safe contact pressure without rubbing of the cam on the frame
- Vibration-proof: successfully tested in accordance to DIN EN 61373
- Different assembly options: the anti-rotation device can be mounted with countersunk screws and if using washers also with cylinder head screws or weld studs
- Two housing lengths: different door thicknesses based on housing length 28 mm and 37 mm allow the versatile use of materials including wood, fiberglass synthetics and sandwich material
- Wide range of H dimensions: design can be varied by the cranking of the cam
