The SLC3-2548 is a heavy-duty compression latch for rail vehicle doors and access panels, operated with a 7 or 8 mm square key. SUS304 body, rated IP65, 700 N ultimate load. Vibration and fatigue test reports are available on request.
- SKU : SLC3-2548
Rail doors fail at the hardware before anything else. The SLC3-2548 is the heavy-duty build of our railway compression pair: a stainless 304 body, a cam that pulls the door into its gasket as it turns, and a square drive that operators can work with gloves on. Catalogue ratings: 700 N ultimate load, unlocking torque no higher than 0.79 N·m, 7 mm of tensioning stroke.
Vibration and fatigue documentation accompanies series production on request. Tell us the standard your project cites and we confirm what reports can be issued for your order.
Compatible with EMKA railway quarter turn class and the Southco E3 series envelope; see the cross-reference table on this page.
Railway buyer's checklist

How To
1. Specify the heavy rail positions
Heavy positions — underframe equipment doors and outer access panels — take the 2548, the heavy-duty build of the railway compression pair.
2. Work it with gloves on
A stainless 304 body and a 7/8 mm square drive let operators work the latch with gloves on.
3. Let the cam pull the door into the gasket
The cam pulls the door into its gasket as it turns; catalogue ratings list 700 N ultimate load, unlocking torque no higher than 0.79 N·m, and 7 mm of tensioning stroke.
4. Ask for the vibration evidence
Vibration and fatigue documentation accompanies series production on request; name the standard your project cites and confirm which reports can be issued for your order.
5. Match panels 1–15 mm at IP65
The latch covers panels 1–15 mm at an IP65 rating, compatible with the EMKA railway quarter-turn class and the Southco E3 series envelope.
