SL-4000-10 Vertical Drive Rotary Lock
The 4000-10 vertical drive rotary lock secures tall cabinet doors and offshore electrical enclosures with a rod-driven mechanism, available in single- or dual-stage versions for left- or right-hand installation.
- SKU : SL-4000-10 · 4000-10 · 4000/10
The 4000-10 features a vertical drive locking mechanism, available in single-stage or dual-stage configurations and adaptable for left-hand or right-hand installation — providing flexible integration across a wide range of equipment door designs.
Striker fixing is achieved via a Φ6.4 through hole or M6×1 threaded mount, ensuring broad compatibility with varying panel thicknesses and mounting conditions. The latch maintains consistent and reliable locking retention under a maximum load of 3,300 N, delivering the structural integrity required in high-stress applications.
Designed for specialised vehicles, vibration-intensive machinery, and sealed dustproof industrial enclosures, the 4000-10 performs dependably in demanding operating environments where standard latches are insufficient.

How To
1. Choose single-stage or dual-stage to match the door travel
The 4000-10 latches in single-stage or dual-stage configurations; match the stage count to how far the door needs to pull in, and confirm left-hand or right-hand orientation before ordering.
2. Fix the striker to the frame first
Striker fixing is via a Φ6.4 through hole or an M6×1 threaded mount; drill and tap the frame before hanging the door so the striker position can be checked against the latch body.
3. Check panel thickness against the mount pattern
The through-hole and threaded options cover varying panel thicknesses — verify your door and frame gauges so the striker sits at the right height for clean engagement.
4. Respect the 3,300 N working load
The latch holds locking retention up to a 3,300 N maximum load; keep linkage friction low and do not use it as a structural hinge on doors that see higher static loads.
5. Specify stainless steel for corrosive sites
For outdoor or coastal installations on special vehicles and dustproof enclosures, order the stainless build so the lock body matches the site's corrosion class.
