Endura Products What's the point of hanging a beautiful composite, vinyl, or fiberglass door on a wood frame that may start weathering within months? Endura's two-piece Prefinished Frame is a durable, low-maintenance solution to this problem. Its thick PVC exterior frame, with an optional integral brick mold, protects the attached wood interior frame from water infiltration. It features mitered corners on jambs and headers, headers routed for mull systems, and an easy-to-install snap-in nailing fin that also provides a continuous weather barrier. Hinge, strike, and deadbolt prep details are built into the frame. 800.334.2006. www.enduraproducts.com.
