Prime-line Products L 5770 Mill Hanger Latch Screen Hardware

Product Description

The PRIME-LINE PRODUCTS L 5770 is a stamped aluminum hanger and latch set used to mount window screens to wood-framed windows. Each pack contains two top hangers, one bottom latch, and one ball head screw — all the hardware needed to secure a 7/16-inch window screen in a single installation. The mill finish aluminum construction resists corrosion and blends with standard screen frame profiles. This is a straightforward, purpose-built fastener set used by window installers, glaziers, and maintenance professionals who need reliable, low-profile screen retention hardware.

The L 5770 is intended for residential wood-framed window applications where 7/16-inch window screens must be secured top and bottom. The included top hangers seat into the upper frame channel while the bottom latch locks the screen in place at the sill. This hardware is commonly used in single-family homes, apartment units, and light commercial buildings during screen installation, replacement, or seasonal changeover. Each pack covers one screen opening, making it easy to stock by quantity of screens serviced.

Key Features

Compatibility

Designed for use with 7/16-inch window screens installed in wood-framed window openings. Consult frame dimensions before ordering to confirm fitment with your specific screen profile.

Installation Notes

Installation is typically performed by window service technicians or general maintenance staff using basic hand tools. Seat the top hangers into the upper frame channel before engaging the bottom latch at the sill. Ensure the window sash is fully closed and the opening is clear before securing the screen. Do not overtighten the ball head screw, as aluminum hardware can strip if excess force is applied to the fastener.
