Interclamp Sizes

Five different size ranges of Interclamp handrail fittings are available as shown in the table, hence a suitable size can be selected for any particular application. Interclamps are easily identified by a type number of each design eg. 125 followed by a size code eg. D48, the latter part of which corresponds with the approximate outside diameter of the handrail tube to be used (48.3mm = 1 ½" nominal bore in this case). Hence a 90° elbow suitable for an 1 ½" nominal bore tube in this example would be denoted as a 125-D48.
