350KG Electromagnetic Lock Guide: 800LBS High Holding Force Maglock

350KG Electromagnetic Lock: When You Need Extra Holding Force

Most single-door maglocks are rated at 280kg. For heavy doors, wide gates and high-traffic entrances, the SK-350 electromagnetic lock steps up to 350kg / 800lbs of holding force.

Why 350kg Instead of 280kg

A 280kg lock is fine for standard office doors. But heavy metal doors, wide fire doors, swing gates and windy storefronts push the lock harder — vibration, wind pressure and forced entry attempts. The 350kg / 800lbs rating gives a wider safety margin for these high-stress applications.

Fail-Safe Release for Fire Compliance

Like every maglock in our range, the SK-350 is fail-safe: when power is cut, the lock releases instantly for safe egress. When the fire alarm cuts the circuit, heavy doors open automatically so people can exit without keys or panic hardware.

Built for Durability

The magnesium-aluminum alloy body is lightweight yet rigid, with a silver anti-rust finish. The sealed construction resists humidity and weather, so the lock holds up outdoors as well as inside.
