500KG Electromagnetic Lock: Maximum Holding Force for High-Security Doors
When a standard 280kg or 350kg lock isn’t enough, the SK-500 electromagnetic lock delivers 500kg / 1200lbs of holding force — the highest in our maglock range.

When You Need 500KG
Heavy metal doors, wide gate entries, high-security main entrances and fire-rated heavy doors push a standard maglock to its limit. The 500kg / 1200lbs rating gives a wide safety margin for these high-stress, high-security applications.

Fail-Safe Release for Fire Compliance
Like every maglock in our range, the SK-500 is fail-safe: when power is cut, the lock releases instantly for safe egress. Even with 500kg of holding force, the lock opens the moment power is lost — fire safety comes first.

Built for Durability
The magnesium-aluminum alloy body is rigid and corrosion-resistant, with a silver anti-rust finish. The sealed construction resists humidity and weather, so the lock holds up outdoors as well as inside — even under heavy daily use.
