Defining Your Product Requirements

To ensure that you obtain the exact Colson product you require, we employ catalogue reference codes that are used at all stages of production. These define your requirements precisely. When ordering, you can be assured of recieving the right castor or wheel every time by using our simple system.

The coding used is a form of shorthand, using letters as abbreviations of words, e.g. RU for Rubber tyred, NY for Nylon, S for Swivel Seal. Castor prefixes are: T = Top Plate, B = Bolt Hole Fixing, S = Swivel Castor, F = Fixed Castor. Numbers are used to give wheel diameters and metric bearing types.  

The maximum length of any product is 17 characters, but in many cases the code will be shorter. For example, the code for a basic castor with a standard top plate will not require the parts of the code reffering to fitting and features, reducing the reference to 10 characters. The example below shows all the characters in use and depicts relevant parts of the complete castor assembly - also shown is a complete wheel reference.
