Screen Tight Base38 Porch Screening Base, Vinyl, Black, 3-1/2 In. X 8 Ft.

The Screen Tight BASE38 Porch Screening Base is a durable vinyl component designed to attach screen material to existing 4 in. x 4 in. wooden framing. This 8-foot base provides a secure, low-profile foundation for DIY and professional screen installations on porches, patios, and window enclosures. By eliminating traditional staples, nails, and loose fasteners, this vinyl base delivers a clean, finished appearance while protecting your frame from moisture and UV damage.

Made from outdoor-grade vinyl, the BASE38 features a precision-milled groove that guides screen spline smoothly and reduces friction during installation. The base attaches to existing framing with wood screws or roof tacks using pre-punched holes spaced at 8-inch increments, requiring no mitering or complex cuts. A snap-on cap (sold separately) evenly tightens the screen material in place without staples, lattices, nails, or loose fasteners.
