Telestrut and Telespar is telescoping tubing that can be used in a wide range of industrial applications. Three sided channel and four sided tubing combine to make a powerful support system that is like no other on the market. By joining infinitely adjustable 3 sided channel with incrementally adjustable, prepunched 4 sided tubing, the Telestrut and telespar square metal tubing systems can be telescoped, spliced, adjusted, and reused faster and easier than anything in its class. This telescoping metal tubing system allows you to design, build, and change support structures faster...and better...than you ever thought possible. Telecoping strut is the most versatile multi-purpose support system ever devised.

Boltless connection system makes use of a special Telestrut rivet to connect sections with a quick hammer blow.

Using channel with holes as the telescoping member, both incremental and infinite adjustments can be achieved with the same assembly.

Telestrut and Telespar telescoping tubing offers incremental adjustment. Simply loosen the connection, push the bolt down, slide the channel to a new position, and re-tighten.
