Add mobility to your Maker Pipe and conduit build with the caster kit! Our casters are on a swivel wheel that doesn't mark up the floor so they are perfect for the home and shop. One caster kit includes four locking casters.  Each caster has an insert pre-applied that fits it securely in the end of the 3/4" or 1" EMT Conduit. Use a rubber mallet to tap the caster insert down into the conduit and finish off your mobile build!
