8 Inch Pneumatic Wheel Set with Plate Mount Brackets 4 Pieces Overview This 4piece pneumatic wheel set replaces ordinary fragile caster wheels and brackets with durable rubber tires and galvanized platemount brackets. The inflatable tires and bearing design improve mobility and reduce wear for longer service life in light industrial and domestic applications. Key benefits Improved mobility: Pneumatic 8 inch wheels absorb shock and roll smoothly for easier movement of heavy or awkward items. Durable construction: quality rubber tires and galvanized brackets resist abrasion and maintain strength under load. Stable and versatile: Two swiveling universal wheels plus two directional (fixed) wheels provide both 360 degree maneuverability and straightline stability. Easy to install: Platemount brackets match common hole patterns for straightforward replacement of existing wheels.
