Galvanised fixed and swivel Norstal clamps are used throughout the Telecommunications Industry as a tried and tested method of fixing two 48mm dia.Tubes for vertical and horizontal applications.

The Fixed Norstal will give 90 degree applications, while the Swivel Norstal can be adjusted to a fixed position of your choice.

Both clamps are fully galvanised for long life

The use of an Increasing sleeve (as shown in the details drawing) will allow you to joint tubes of different diametres - the IS 1 1/4" will increase the relevent area of an 1 1/4" dia. tube to suit the clamp at 48mm and the IS 1 1/2" will allow the use of an 1 1/2" tube..
