Prime-Line Aluminum Screen Frame, 3/4 x 5/16 x 72 in – White

Overview

Turn damaged or missing window screens into a clean, functional setup with the Prime-Line Aluminum Screen Frame. This kit includes 20 white pieces crafted from 0.020 inch thick aluminum, each measuring 72 inches in length. Paired with Prime-Line MP7729 5/16 inch x 3/4 inch square cut plastic corners, it offers a straightforward path to build or replace high-quality window screens. The durable white finish blends with most window styles, providing a polished look as you customize your screen project.

Why it helps your windows

The lineal frame pieces are intentionally cambered (slightly curved) outward, designed to resist inward bowing as you install and tension the screen cloth. That design choice helps maintain a taut, even surface, which contributes to a neater, more durable end result that holds up to daily opening and closing.

Whether you’re repairing a single window or restoring several, this frame set is built for versatility. The frame works with a range of screen fabrics and can be assembled into ready-to-install screens that suit your home’s needs.

What you can create

• Build fresh window screens from scratch for a seamless look and reliable fit.
• Repair missing or damaged frames, restoring function and airflow without a full replacement.
• Pair with solar screen fabric to craft sun screens that reduce glare while maintaining visibility.
• Benefit from a thicker spline channel that adds support and helps hold fabric securely in place.

Materials, compatibility, and sizing

• Material: Aluminum, 0.020 inch thick, in a durable white finish.
• Length: 72 inches per piece; 20 pieces included.
• Spline guidance: 0.185 inch for standard fiberglass cloth, 0.165 inch for aluminum screen, 0.155 inch for solar/pet screen.

Installation tips

For screens over 48 inches in height or width, consider adding a spreader bar with compatible clips to minimize bowing and maintain a clean edge. Prime-Line MP14138 and MP7794 are recommended options to pair with larger projects. When using solar or other specialty fabrics, ensure you select the appropriate spline size to maintain tight, even fabric tension.

Practical benefits

Using this aluminum frame kit can help you achieve a tidy, custom look for window screens while offering practical flexibility. The ability to create or repair screens with your preferred fabric type expands your options for privacy, sun control, and airflow. While results may vary by materials and window, the frame is designed to support confident, hands-on customization.
