Kee Safety 72-8 Kee Klamp Stair Tread Support

Type 72 is a stair tread support suitable for most types of stair tread, including timber, open steel and checker plate. Fixing of the treads is by two bolt holes in each fitting. Ø indicates diameter of fixing holes. (Special Order Only). If Type 72 fittings are to be used for a permanent application or subjected to high loads, the stair tread support pipe which is located at its ends with a single set screw, should be drilled and pinned to avoid rotational slip.

Kee Klamp® Galvanized Steel Components

Steel pipe is an inherently efficient structural component. It is strong, has no sharp corners, and is readily available worldwide. The difficulty in using steel pipe to form structures arises when joining. Threaded pipe must be supplied in set lengths making for zero flexibility in installation. Welding is labor intensive, requires a highly skilled workforce, and specialized equipment. The answer is KEE KLAMP® components. The underlying principle is simple but highly effective: use slip-on components to create versatile and rigid tubular structures. The Kee Klamp® principle has been developed and refined for more than 75 years resulting in an extensive range of components suited for any need.

Features:

• High corrosion resistance
• No welding or threading
• Galvanized for long lasting protection
• Recessed screws for a smooth look
• Quick installation
• Large set screws resists thread stripping
• Schedule 40 Pipe sizes 1/4" - 2"
• The Kee Klamp® Fitting

The simple but effective engineering principle of the Kee Klamp® fitting is the foundation of the most versatile pipe connection system available. There are many variations of fitting to suit a wide range of applications, thus providing the versatility to achieve virtually any structural configuration.

Kee Klamp® fittings are iron castings manufactured to the requirements of ASTM A47-77-32510. A range of fittings to suit eight sizes of pipe is available. Hex set screws firmly lock the pipe into the fitting. Set screws are manufactured in case hardened steel and are protected against corrosion by Kee Koat®.

A Kee Klamp® fitting (size 5 to 9) can support an axial load of *2000 lbs. per set screw with the set screw tightened to a torque of 29 lbs./ft. This is normally obtained when the set screw is fully tightened using a ratchet wrench.

Kee Safety components are approved by TÜV, Europe’s leading independent testing house. The maximum load of each fitting type is as stated on the TÜV Certificate.
