need help identifying this tubing
just bought this bench bike clamp:
Bench Mount Bike Repair Stand w Clamps Countertop Bicycle Cycle Kit Tool | eBay
and id like to modify it so that i have a longer "arm". at its current stock arm length im having a hard time working on the other side as its too close to the bench its mounted to.
tried to go to lowes, homedepot but cant find the same kind of tubing or anything with the same I.D. which looks like 1.25 in ....
thanks for your help guys and advance happy thanksgiving.
