The simple but effective engineering principle of the Kee Klamp and Kee Lite fitting is the foundation of a versatile tubular connection system. 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® tubular fittings are generally made from cast iron and are manufactured to the requirements of EN 1562 & EN 1563 and galvanized to the requirements of EN ISO 1461. A range of Components to suit seven sizes of tube is available. A simple hexagon key is the only tool required to create a strong, rigid joint. A recessed grub screw tightened by the hexagon key, firmly locks the tube into the Component. The grub screw is generally manufactured in case hardened steel and benefits from Kee Koat® protection against corrosion. This combined with the ThredKoat® (patented) factory applied coating for the threaded recesses ensures that Kee Klamp® tubular fittings achieve longer life and better corrosion resistance.
A Kee Klamp® Component (size 5 to 9) can support an axial load of *900 Kg (2000 lbs) per grub screw with the grub screw tightened to a torque of 39 Nm (29 lbs. ft.).
Kee Lite® fittings are made from a high grade Aluminium silicon magnesium alloy. The fittings are strong yet light and extremely durable even in harsh environments. They are only one third the weight of iron fittings, with about 75% of comparable tensile strength. Kee Klamp® and Kee Lite® fittings are designed to suit BS EN755 tube.
Tube
Kee Klamp and Kee Lite fittings are produced in a range of standard sizes to suit steel tube, size 20mm nominal bore to 50mm nominal bore; also equivalent sizes of tubing in other materials.
Tube sizes are shown in the table and sectional drawings below.

The maximum load of each fitting type is as stated on the TÜV Certificate, a copy of which is available upon request. The technical descriptions featured in this manual have not been part of the testing.
Due to possible dynamic load influences, some structures will need to be checked at regular intervals to ensure set screws are correctly tightened.
Specifying Klamp® or Kee Lite® Fittings
The information contained in this manual includes everything required to produce a full specification.
Every fitting is illustrated and has a simple numerical code reference, which defines the type of fitting and the tube size, or sizes, it is designed to receive.
The first number, preceeding the dash (-) identifies the type of Kee Klamp® or Kee Lite® fitting.
A single digit, following the dash, defines tube size. Two digits after the dash indicate that the fitting is designed to receive two sizes of tube. Likewise, three digits after the dash indicate that the fitting is designed to receive three sizes of tube. The Kee Klamp® or Kee Lite® tube size codes are shown on pages 4 and 5 of this manual, where the Kee Klamp® or Kee Lite® tube code is related to actual tube dimensions.
