Strut Mounted Cushion Clamp Assembly Numbers

Ordering is simple.

  1. Determine if you require tube or pipe series.
  2. Determine the size of the line to be clamped.

All standard clamp assemblies consist of a 6-digit part number. A complete listing of part numbers for the pipe and tube series is listed on pages 5-6. The clamp assemblies are listed by series 100 and 200 as shown

  • 100 - tube (O.D. tube)
  • 200 - pipe (Normal pipe)

The cushion size is indicated by decimal inch. The example will show how to order both tube and pipe series.


All standard strut mounted cushion clamps have the following features:

  • Cushion material is a thermoplastic elastomer rated from -65° to +275°F
  • Clamps are 1008 - 1010 carbon steel
  • Studs are projection welded
  • Nylon insert locknut
  • All metal components have a Tri-Valent (non-hex) plating
