    Insist on 6061-T6 drawn tubing for strength, durability, and precise fit.  Extruded tubing looks similar, but it is not as strong or durable.  Extruded parts are prone to failure, while drawn parts keep performing.  Drawn material offers the same strength as hex without the additional weight.

    •  2-1/4” of tapped thread on each end.

    Tech Tip:  Tube length will need to be 4" shorter than eye to eye working length.
