Calipers
Tube calipers or hole measuring instruments are stocked by us from Elliott, Airtool and T.C Wilson. Depending on the size of the tubes your are working on you can purchase a specific tube caliper to measure the tube hole, the finished dimension after the tube has been rolled to insure proper roll crush.
We carry the tube calipers in different lengths as well.
Please give our tool sales person a call for your caliper measuring requirements.
