Frequently Asked Questions

Is 1-1/2 inch a common tube size?
Yes. 1-1/2 inch ID tubing is very common for industrial furniture, workbenches, and heavy-duty equipment frames.
What is the max load for these?
Load capacity depends on the specific wheel and caster selected. Check individual product listings for ratings.
How do expanding adapters compare to plate casters?
Expanding adapters are easier to install (no drilling) but are generally for lighter loads than bolted plate mounts.
