Replacement Swivel Caster Set 4in with Brake - Fits Rubbermaid 7734-88

Our review of these replacement swivel casters for the Rubbermaid Mobile Work Center 7734-88 finds them to be a straightforward, practical fix for a common problem: worn or damaged wheels. Intended for owners of the Rubbermaid 5-drawer mobile work center who need a reliable, quiet rolling solution, the package includes two Service Caster Series #05 swivel casters with 4in thermoplastic rubber wheels and side locking brakes. The single biggest reason to buy is the combination of a precise fit and smooth rollability, which restores maneuverability without replacing the entire cart.

Key Features

• Exact fit: Designed to replace the casters on the Rubbermaid Mobile Work Center 7734-88 so installation aligns with the original mounting points.
• 4in thermoplastic rubber wheel: The wheel material delivers quiet operation and a cushioned ride across hard floors, reducing vibration and noise.
• Side locking brake: Each caster has a brake that secures the cart in place for stable work or storage when needed.
• Dual ball bearing: Bearings and heat treated raceway construction promote smoother rolling under light duty loads.
• Weight capacity: Each caster supports up to 125 lbs, providing a combined capacity of 250 lbs for typical work center loads.
• Set of two: Supplied as a pair so users can replace two casters at a time for balanced performance.

Who It's For

This set is best for home workshop owners, office maintenance staff, and light industrial users who already own the Rubbermaid Mobile Work Center 7734-88 and want a direct replacement to restore mobility. It is especially suited to those who value quieter, smoother rolling on hard floors and need the ability to lock the cart in place.

Those who need replacement hardware, heavy duty casters, or greater than 250 lbs total capacity should look elsewhere, since the listing notes that hardware is not included and the Series 05 casters are intended for light duty use rather than heavy industrial loads.
