ERCO Pipe Calipers
The pipe caliper is used to measure the size of all types of pipes (Copper, Iron, PVC, CPVC, Schedule 40, 80, etc). Simply put the pipe in between the two wings of the caliper and close the wings tight to the pipe (making sure the pipe touches the top of the caliper and two wings of the pipe caliper). The pipe caliper will then show you the size of the pipe. This pipe caliper can be used to measure pipes as small as 1/4″ all the way up to 12″ pipes.
Pipe Caliper is die cut steel that is nickel plated giving it a nice chrome finish.
