The new design is 4.3 oz lighter per assembly! Tube coupler/interlocks for 1.625 or 1 5/8" diameter tube with .083" thickness. This size tubing is mandated in most NHRA Chromoly cage work and is a popular size of tubing for drag racing oriented shops.


The couplers are a safe and effective way to make elements of your tube work removable or break down for shipping purposes. These are what we use in all of our Bolt in Chromoly roll bars and parachute bars.
