How to install Expanding Rubber Stem Casters

Step 1. While holding the swivel bearing ( A ) turn the thin round nut ( B ) above the rubber sleeve clockwise. This will expand the rubber sleeve ( C ) . Expand the rubber sleeve until it is a very snug fit going into your tubing.

Step 2. Insert the entire stem ( D ) all the way up into your tubing.

Step 3. Turn the swivel bearing ( A ) counter clockwise to further expand the rubber sleeve ( C ) inside your tubing. To further tighten, with a wrench, turn the hex nut ( E ) under the swivel bearing counter clockwise.
