Prime-line G 3133 Sliding Window Roller Assembly 2 Pack

Product Description

The PRIME-LINE PRODUCTS COMPANY G 3133 is a bottom roller assembly designed for heavy sliding glass windows. It features an adjustable steel housing paired with a steel ball bearing, center-grooved wheel measuring 27/32 inches in diameter. This roller assembly allows smooth, controlled movement of sliding window panels and can be adjusted to account for minor frame variances. It is typically installed by glaziers, general contractors, or experienced window service technicians performing hardware replacement on residential or light commercial sliding window systems. Each package contains two roller assemblies.

This roller assembly is suited for use as a bottom-track roller on heavy sliding glass windows where reliable, low-friction movement is required. The center-grooved wheel profile seats securely on standard bottom track channels, keeping the window panel aligned during operation. The adjustable steel housing accommodates slight variations in frame height, making it a practical choice for retrofit and replacement applications where the original hardware has worn or failed.

Key Features

• Center-grooved steel ball bearing wheel for smooth, low-friction sliding operation
• Adjustable steel housing to accommodate minor frame height variations
• 27/32 inch wheel diameter fits standard heavy sliding glass window bottom tracks

Compatibility

Installation Notes

Installation is typically performed by a glazier or qualified window hardware technician. Before servicing, ensure the window panel is fully supported and cannot shift or fall during roller removal and reinstallation. Use appropriate hand tools to adjust the housing set screw once the roller is seated in the bottom track, confirming smooth travel across the full width of the frame before completing the job.
