SL-A03/A04 Standard Toggle Latch
The SL-A03/A04 is a standard toggle latch series in SPCC steel or SUS304 stainless with a built-in self-resetting spring: the A03 is the plain version and the A04 adds a locking facility, both 112 mm long with 200 N clamping force and 800 N ultimate load - a general-purpose fastener for equipment covers and cases.
- SKU : SL-A03-A04
Toggle latches clamp over-center: the lever geometry locks itself at the end of travel and resists opening under vibration, while releasing in one hand movement for frequent access. Choose steel (SPCC, plated) for dry indoor service and SUS304 stainless for humid, washdown, or coastal duty. Clamping force and ultimate load are per-model ratings - size the latch to the gasket compression and expected vibration, and confirm dimensions per drawing.

How To
1. Start with the general-purpose fastener
The standard toggle latch series covers equipment covers and cases that need simple, positive clamping.
2. Use the self-resetting spring
A built-in self-resetting spring returns the lever to position after every open-close cycle.
3. Pick plain or locking
The A03 is the plain version and the A04 adds a locking facility; both are 112 mm long with 200 N clamping force and 800 N ultimate load.
4. Let the geometry self-lock
The lever geometry locks itself at the end of travel and resists opening under vibration.
5. Match material to the site
Choose SPCC plated steel for dry indoor service and SUS304 for humid or coastal duty, and confirm the plating against salt-spray exposure.
