Round Steel Telescopic Tubing

Round Steel Tubing

Round steel telescopic tubing is suited for applications calling for extreme strength or need to weld to a steel plate or base. Testrite typically stocks only 7/8” and 1” diameters, but can readily get others in quantity. The lock we recommend for steel tubing is our “B” collar lock or cotter pin. Steel tubing requires a powder coated finish which we can supply in any color.
