Presenting the Hamilton R-7112-PRB, an industry-leading swivel caster equipped with a 12-inch pneumatic air-filled tire. Designed to deliver unparalleled performance, this caster is the epitome of engineering excellence and quality from Hamilton.
The zinc-plated finish isn't just about aesthetics. It offers exceptional rust resistance, ensuring your caster remains durable even in demanding environments. This finish also adds an extra layer of protection, enhancing the caster's longevity.

The 12-inch tire is not only large but is also air-filled, providing optimal shock absorption. It's particularly effective on uneven grounds, ensuring that the contents remain stable and the journey remains smooth.
Equipped with a 3/4" precision ball bearing, this caster promises seamless rotation. The reduced friction means enhanced mobility, making it easier to maneuver equipment, regardless of its weight.
Hamilton has always been a beacon of quality and innovation in the caster industry. This product, with its durable construction and user-friendly design, continues that legacy, making it a favorite among both professionals and DIY enthusiasts.
