The LM9300 Series is part of a three-point locking system designed for tornado, hurricane or high security applications, providing superior protection with familiar operation. Latches at the top, side and bottom of the door provide protection from high wind speeds and 15-lb. projectile impacts up to 100 mph when paired with a Steelcraft Paladin tornado resistant door. 

In the event of a tornado, all openings to a storm shelter must be secured – including windows. For this reason, LM9300 is available in a shutter configuration. The storm shutter utilizes a 4-sided hinged frame that mounts against a window from the inside of the shelter to protect the occupants from flying glass and debris. 

Ideal for use on:    

  • Doors requiring hurricane protection (with Steelcraft H door)
  • Tornado shutters (with Steelcraft Paladin door) 
  • Loading dock pair doors
  • Kitchen exit pair doors 
  • Multi-point latching doors requiring lock status indication trim
