DP-50 The SPD Sliding Patio Door System offers value and performance for the patio. The low maintenance PVC frame and sash provide durability and smooth operation. The SPD Sliding Patio Door System comes fully assembled and ready to install. SPD also features a DP-50 performance rating, which assures that the SPD Patio Door System can withstand 171 mph winds, water penetration of 8” of rain per hour driven by 54 mph winds and air infiltration equal to 25mph winds. This vinyl patio door features a 4-5/8" frame that can be adapted to fit nearly any wall thickness. The "fixed" panel is actually part of the frame, producing a stronger, more dimensionally stable frame. It features a removable integral fin on all four sides and a field-reversible system to allow last-minute sash handing change on-site if necessary.  The SPD also features a full-length aluminum reinforcement extrusion at the panel meeting rails for increased strength and dimensional stability. There is an anodized metal sill cap and a mono-rail rolling track that is corrosion-resistant and very durable. A top quality extruded aluminum frame screen with easy-glide rollers, fiberglass mesh and locking handle is available. The active sliding panel or sash features fully adjustable tandem roller trucks with solid nylon rollers and steel bearings for silent, smooth operation. The stainless steel coastal kit includes 2 stainless steel rollers and stainless steel screws for ALL exterior exposed fasteners. The SPD is available in White or Sand.

Standard dual-point lockset ensures that the SPD vinyl sliding patio door system is just as secure as any entry door. As added security, a footbolt is available as an optional upgrade. An optional keyed lock is available. Multiple Dual-Durometer glazing stops provide added energy efficiency. 7/8" insulated glass is available with low-E as an optional upgrade.
