Making your own telescoping tubing assembly and just want to buy our strongest telescoping lock? The B Split Collar Lock is ready for online ordering!

As a sizing example: The 1-1/2" to 1-3/8" B Lock is designed to accept a 1-1/2" Diameter OD tube on one end, and a 1-3/8" Diameter OD tube on the other end. Lock tightens onto tubing with tension, no adhesive required!

Note - These locks are designed to be used with our tight tolerance round tubing. We recommend purchasing samples of these telescoping clamps to test with your tubing before large runs, as your tubing sizes and ovality may vary.
