Prime Line Products M 6003 Tub Enclosure Roller 7/8 in 2 Pack

Product Description

The PRIME LINE PRODUCTS M 6003 is a 2-pack of 7/8-inch flat ball bearing tub enclosure rollers designed for sliding shower and tub enclosure door systems. Each roller features a threaded hex hub for secure, adjustable mounting. The ball bearing construction supports smooth, consistent door travel and resists the wear that comes with daily use in wet environments. These rollers are a direct replacement-style component installed by plumbers, tile contractors, and general maintenance technicians when existing rollers crack, flatten, or lose smooth operation.

This roller is suited for residential and light commercial tub enclosure doors that use a top or bottom track sliding configuration. The 7/8-inch wheel diameter fits a range of standard sliding glass door enclosure hardware. The threaded hex hub allows precise height adjustment during installation, making it useful when re-hanging doors on worn or misaligned tracks. Typically installed as part of a door rehang or hardware refresh on bathtub and shower enclosure units.

Key Features

• 7/8-inch flat roller wheel with ball bearing core for smooth door travel
• Threaded hex hub allows height and tension adjustment at install
• 2-pack format covers both rollers on a single door panel in one purchase
• Designed for wet-environment durability in tub and shower enclosure applications
• Carded packaging for easy retail and service van storage

Compatibility

Designed as an OEM-style replacement roller for residential sliding tub and shower enclosure door assemblies using 7/8-inch flat-style track rollers with threaded hex hub mounting.

Installation Notes

Installation is typically performed by a plumber or general contractor during a door hardware service or full enclosure rehang. Before replacing rollers, fully remove the door panel from the track and work on a stable, padded surface to avoid glass damage. The threaded hex hub should be tightened securely and adjusted so the door glides without binding or lifting off the track. Follow the enclosure manufacturer's guidance for door weight limits and track alignment before returning the door to service.
