Prime Line Products B 515 Screen Door Tension Spring 2 Pack

Product Description

The PRIME LINE PRODUCTS B 515 is a sliding screen door tension spring designed to maintain proper door tension and smooth roller engagement in residential sliding screen door assemblies. Each spring measures 1.25 inches and features a concave roller profile that keeps the door tracking correctly in the frame channel. This hardware component is typically installed by window and door technicians, general contractors, or experienced DIYers performing screen door maintenance or replacement repairs. Two springs are included per pack, making it a practical option for single-door service calls or keeping a spare on hand.

The B 515 is suited for standard residential sliding screen door applications where the existing tension spring has worn, broken, or lost its holding force. The concave roller design seats firmly in the door track, reducing the chance of the door jumping the channel during operation. This part ships in carded retail packaging and is sold as a 2-pack unit, with a package quantity of 6 units available per order increment for restocking purposes.

Installation Notes

Installation is performed by door and window technicians or qualified DIYers with basic hand tools. Before servicing, ensure the screen door is removed from the track and laid flat on a stable work surface to prevent injury and damage to the frame. Tension springs store mechanical energy and should be handled carefully during removal and installation to avoid snapping. Follow the door manufacturer's service instructions for proper spring seating and roller alignment before reinstalling the door in the track.
