Prime Line Products B 551 Screen Door Roller 1 Inch 2 Pack

Product Description

The PRIME LINE PRODUCTS B 551 is a nylon screen door roller assembly sold in a 2-pack. Each roller measures 1 inch in diameter and is designed to allow smooth, low-friction travel of a screen door along its track. The nylon wheel construction resists corrosion and wear under regular residential use. This type of hardware is typically installed or replaced by general contractors, handymen, or experienced DIYers performing screen door maintenance or repair. The assembly is carded for retail and comes two units per package.

This roller assembly is suited for screen door replacement and repair applications in residential settings. It is specifically noted to fit Air Control brand doors. The 1-inch diameter wheel size is a common specification for lightweight aluminum and vinyl-framed screen doors. Having two rollers per pack covers a standard single-door replacement, which typically requires one roller at each bottom corner of the door frame.

Installation Notes

Screen door roller assemblies are typically replaced by general contractors or skilled DIYers using basic hand tools. Before servicing, lift and remove the screen door from its track to avoid injury and damage to the frame. Inspect the track for debris or deformation before installing new rollers, as a damaged track will reduce roller service life. Confirm roller diameter and frame slot dimensions match before installation.
