Product Overview

CRL Flat Tension Springs are specifically designed to securely hold screens in the window channel. To install, you will need to drill two 3/16" (4.8 mm) diameter holes 3-1/8" (79.4 mm) center-to-center. We highly recommend using the CRL WST900 Notching Jig and Tool for a seamless installation of the spring into the base of a 5/16" or 3/8" (7.9 or 10 mm) screen frame.

Notable Features:

• Fits 5/16" to 3/8" (7.9 to 10 mm) Screen Frame
• Keeps the Screen Frame Tight in the Window Channel
