If anyone is looking for casters to mount on their stands and they don't have a washer welded to the bottom of the metal tubing, I bought these 4 inch casters with the ER rubber stem (rated for 1200 pounds) and they work great! http://www.castercity.com/eshop/10Expand.asp?ProductCode=3APA4X-ML&ReturnTo=../cm3a-stem.htm
I have 1 1/2 inch square tube with 1 3/8 inch internal diameter. The brakes on these swivel casters not only lock the wheel but also lock the swivel in place as well.
Click on the link below and then click on the installation instructions for the ER stem caster to see how they install.

The rubber expanded very well inside the tubes of my stand, and the caster is locked in and is very secure. Just thought I'd post this if someone is deciding on what to purchase if they don't have a washer on the bottom of their stand legs. These are very high quality casters and they are custom made to order.
