Hot Buttons Dolly Wheels(Set of 4)

<p>Hot Buttons work beautifully with Matthews Doorway Dolly (click to view the Doorway Dolly) or the even more versatile Round-d-Round Doorway Dolly (Click to view the Round-d-Round). <br /> <br /> For straight or curve track, steel, aluminum, or PVC pipe, simply remove the locking nut, self-contained wheel and tire from each axle and replace with Hot Button set and nut. <br /><br /> Hot Buttons also make a perfect scooter dolly with just two axles and any size ordinary plywood. Combination Track/Stage Wheels #395001 are as simple to change as the Hot Buttons. <br /><br /> These wheels have self-contained bearings designed to work on hard surfaces or 1-1/2" diameter straight track only. <br /><br /> Please note Hot Buttons may only be used on 45 degree or 20' diameter track.</p>
