Add these Swivel Casters to any of our Stainless Steel Bases to create a mobile base for your arrangements. Casters have a threaded stem that threads into the base, securing them so they will not wobble or fall out. Swivel bearing and axle have grease fittings. 5-in. (12.70cm) diameter wheels allow for easy movement throughout your facility. Base with Casters adds 6.75 in. (17.15cm) to Cage Arrangement height. Bases up to 6-ft.
