Floor Hatch Safety Railing, Also Available Part of the KeeHatch family of products, the Floor Hatch Safety Railing is designed for safe egress and ingress through access hatches and for fall protection for the floor opening while the access door is up. The railing system uses the industry leading Kee Klamp fittings and is easy to assemble. The Floor Hatch Safety Railing kits are made with either galvanized 11/4' pipe or aluminum 11/2" pipe for all hatch sizes. Installation is easy. For a standard installation, drill 2 holes for each base fitting (Type 62) and use lag bolts size 3/8' x 21/2' and lag shields to fix railing bases in place (lag kits sold separately). If the system is required to be removable, use ground socket fittings (Type 66) that are installed flush with concrete. All set screws should be tightened to 29 lbs/ft during installation. A 2 sided kit can be ordered if the floor hatch backs to the wall. The Floor Hatch Safety Railing can also be custom designed accommodate a toeboard if needed.
