TruFast Plasti-Grip PMF 2-in-1 Anchor and Fastener is engineered for permanently securing rigid or semi-rigid insulation to concrete, masonry, brick, block or stone substrates. Featuring an innovative solid plastic design, it effectively minimizes thermal bridging by eliminating the need for metal pins, screws or adhesives. This ensures improved insulation efficiency and energy performance. Trusted by professional contractors, architects and insulation installers.Installation is quick and straightforward: simply drill a 5/16 in. hole into the masonry substrate and hammer the anchor flush. No specialty tools, adhesives or screws required, making it ideal for rapid, cost-effective installations. The large 2-3/8 in. Dia washer head securely holds insulation in place and features a textured surface, enhancing basecoat adhesion-perfect for EIFS (Exterior Insulation and Finish Systems).
