Rotary latch

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.
