The SL-4001-22 Bottom Drive Rotary Latch is engineered for light- to medium-duty industrial door panels and vehicle enclosures where installation space is restricted. Its compact bottom drive structure allows flexible actuation routing beneath the latch body, and versions are available with or without a mounting bracket to suit different panel layouts. Mounting is via Ø4.5mm through holes or M4×0.7 / 8-32 UNC threaded fasteners. Offered in zinc-plated steel or stainless steel, the latch features an integrated cushioning device for quiet, vibration-resistant closing and withstands ultimate loads up to 2600N — a dependable choice for dust-proof sealed enclosures, equipment covers, and high-volume assembly projects.

How To
1. Route the actuation beneath the latch body
The bottom drive structure is for panels where side or top routing is blocked; run the linkage under the latch body and confirm it clears the door edge through the full swing.
2. Decide on the bracket before drilling
Versions with or without a mounting bracket fit different panel layouts; order the bracket version when the panel face needs a defined standoff, the bracket-less one when space is minimal.
3. Fix through Ø4.5mm holes or M4×0.7 / 8-32 UNC threads
The mounting pattern matches the 4001 family; panels already drilled for a 4001-11 accept this model without rework.
4. Keep the cushioning device engaged
The integrated cushioning device quiets closing and damps vibration; make sure the bracket version is torqued down evenly so the damper does not bind.
5. Respect the 2,600 N ceiling
Ultimate load is 2,600 N; on dust-proof sealed enclosures the gasket stack-up must not push the latch past this rating.
