Specifying Kee Klamp Fittings
The information on fittings in this site is comprehensive, and because of the coding system we have adopted, easy to use.
Diagrams are shown for each fitting showing entry of tube/pipe, a table of dimensions and a definition of use adjacent to its appropriate Type number (10, 15, 20, 25 etc.).
Alongside the Type number is a code (4, 5, 6, 7, etc.) relating to the outside diameter of the tube/pipe for which the Kee Klamp had been designed. The relationship between the Kee Klamp tube/pipe reference and standard tube/pipe outside diameter is explained in the aforementioned chart.
Example: (1) A 10-7 is a Type 10 Kee Klamp fitting with both sockets designed to accept a tube/pipe that has an outside diameter of 42.4mm or 1-11/16" (1-1/4" Nominal Pipe Size). (2) A 25-9 is a Type 25 Kee Klamp fitting with all three sockets designed to accept a tube/pipe that has an outside diameter of 60.9mm or 2 3/8" (2" N.P.S.).
Where more than one tube/pipe reference is shown alongside a particular Type number, it indicates that the individual sockets are designed to accept different sizes of tube/pipe. In a multi-digit code number the first figure relates to the 'A' socket and the second to the 'B' socket. Example (3) A 45-76 is a Type 45 Kee Klamp fitting with 'A' socket accepting a tube/pipe that has an outside diameter of 42.4mm or 1-11/16", and a 'B' socket accepting a tube/pipe that has an outside diameter of 33.7mm or 1-11/32".
While Kee Klamp can give a general guidance relating to the use of each Kee Klamp fitting detailed in this site, the nature of the product means that the ultimate responsibility for selecting the correct fitting for an application must lie with the customer.
The customer should also ensure that the existing structure to which the Kee Klamp construction is being secured, is of sufficient strength to support both the self weight of the Kee Klamp construction and the imposed loads applied, including wind loads, snow loads, and any other superimposed loads.
