SL-A56 Concealed Adjustable Toggle Latch
The SL-A56 is a concealed adjustable toggle latch whose under-center mechanism hides all mounting hardware and the locking function beneath the handle for secure off-plane locking: 500 N clamping force, 2000 N ultimate load, in SPCC steel or SUS304 stainless, with padlock or self-locking versions against accidental opening.
- SKU : SL-A56
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. Hide the hardware under the handle
The concealed adjustable toggle latch hides all mounting hardware and the locking function beneath the handle for secure off-plane locking.
2. Clamp at 500 N
The under-center mechanism delivers 500 N clamping force with a 2000 N ultimate load rating.
3. Let the geometry lock itself
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.
4. Pick steel or stainless by the site
Choose SPCC steel plated for dry indoor service and SUS304 stainless for humid, washdown, or coastal duty.
5. Size it to the gasket and add a padlock
Size the latch to the gasket compression and expected vibration, confirm dimensions per drawing, and pick the padlock or self-locking version against accidental opening.
