Prime Line Products P 7503 Spline Rolling Tool Nylon Wheel

Product Description

The PRIME LINE PRODUCTS P 7503 is a standard duty plastic rolling tool fitted with a nylon wheel, designed for installing window and door screen spline. The tool ships in a package of 10 and accommodates spline sizes from .115 to .165 inches. Both the convex and concave wheel profiles measure 1-5/8 inches in diameter by 3/32 inches in width, giving the installer the right geometry to seat spline cleanly into the frame channel without cutting or stretching the screen material. Weighing 1.79 pounds per package, these tools are lightweight and suited to repeated daily use on residential and light commercial screen work.

This rolling tool is used during window screen and door screen installation and repair. It is the standard choice for screen shops, glazing contractors, and HVAC or building maintenance crews who routinely replace window screens. The dual-profile wheel design allows the installer to switch between convex and concave wheel orientations depending on the spline channel geometry of the screen frame being serviced. Compatible spline sizes of .115 to .165 inches cover the most common residential aluminum and vinyl screen frame profiles.

Compatibility

Designed for use with screen spline in the .115 to .165 inch size range, fitting standard residential and light commercial aluminum and vinyl screen frame channels that accept spline in that diameter.

Installation Notes

Screen spline installation is typically performed by glaziers, window service technicians, or building maintenance personnel and requires no power tools or special trade licensing. Before replacing spline, remove the old spline fully and inspect the frame channel for burrs or debris that could damage the new screen material. Use the convex wheel to press spline into the channel and the concave wheel to guide and seat it evenly. Avoid applying excessive downward force, which can stretch or tear the screen mesh.
