Designed to fit all standard models offered by the manufacturers of roof hatches, the new KeeHatch roof hatch railing system from Kee Safety, Inc. is designed to be installed by one person in less than 30 minutes. Used for safe egress and ingress through roof hatches, and fall protection when a hatch is open, the lightweight aluminum railings affix to the hatch and do not penetrate the roof itself.
