How to Install Expanding Stem Casters

1. Squeeze element by holding bottom of stem (with a wrench, or by hand in some cases), and twisting the top nut.  This will bring the top nut down and cause the rubber element to bulge out.

2. Check to see if caster stem will slip into hollow leg.  It should be hard to push into the leg.  If it slips in too easily, then you may need to squeeze the element again as described in step one.

3. Once snug in place in the leg, the friction should keep the element from slipping while you tighten it a little more.  The caster should now be securely in place.  This procedure will work for both round and square leg.
