B Split Collar Lock 7/8" OD to 1" OD

The B Lock is Testrite's strongest telescopic tubing lock. These telescopic locks are designed to pair beautifully with our telescopic aluminum tubing.

The B Lock is a Split Collar Lock. This Black plastic lock includes plated steel hardware and phenolic S knob

These adjustable tubing clamps are used for telescoping a 7/8" Diameter tube inside of a 1" OD tube. This adjustable tubing lock is perfect engaging a 0.875" tube inside of a 1" tube. The lock serves two functions, both to reduce the play between the inner and outer tube, as well as to lock or clamp the inner tube into a fixed position in relation to the outer tube.

Size refers to the Outside Diameter (OD) of the tubing - larger diameter is fixed, smaller diameter slides through. Bulk packed - Ships FAST.
