The Screen Block base includes 3 retainer strips — one to hold screen, one to hold plastic film and one to cover/hide the fasteners.

The 1.5 inch base mounts to existing porch framing using 2-inch screws (sold separately) spaced approximately 10 inches apart (10-12 screws per 8 foot piece).

Hidden Fasteners for a Clean Look

Screen Block’s retainer strips hold screen and Winterview plastic film in place and an additional trim piece hides all fasteners in the middle of the track, resulting in a sleek, seamless appearance.

How To Install:

Measure & Plan

To install Screen Block, you’ll need an existing porch frame in good condition. Begin by measuring the horizontal dimension of each opening you’re planning to screen.

Cut & Install Base

Cut a piece of the screen block PVC base to the proper length with a chop saw. There is no need to miter the corners. Just keep the base the same distance in from the edge so that all sides will line up properly. Use 2 inch screws every 10 inches or so apart to secure it on the top and bottom.

Install Screens & Plastic Film

Using the retainer strips, install your screen and plastic film. There are three strips — one is used for holding the screen, another for the Winterview plastic film and one to cover the screws. Use the retainer strip to hold the screen in place, tapping it back into the channel with a rubber mallet. Work across the top, sides and bottom, the screen will tighten as you go. Trim off any excess screen with a utility knife. Then repeat the process for the plastic film.

Screen Block can be installed along side any existing screening, such as original Screen Tight.
