CRL Satin Anodized 4" Tapered Door Rail Without Lock for 1/2" Glass - 9-1/2" Patch - DR4TSA12P

Our innovative glass entrance system, the CRL Wedge-Lock® Door Rail System features the exclusive CRL Wedge-Lock® Securing System (U.S. Patents 6,434,905 and 6,912,818 B2, Canadian Patent 2,419,706, and European Patent No. EP 1 404 939 B1). A totally new concept for securing the glass in the door rail. It works by applying pressure from the bottom of the door rail, using two glass retaining aluminum extrusions via a flat stainless steel bar. As this bar is pulled down with socket head cap bolts, pressure is applied to the glass retaining aluminum extrusions. The bottom of the extrusions are at an angle and fit into an angled groove in the door rail. As the glass retaining extrusions are being pulled down, the angled wedge in the door rail also pulls the glass retaining extrusions together. This action, along with our specially designed door retaining gasket, creates a tremendous amount of force (more than 900 lbs.) in our 9" (228.6 mm) Corner Rail. That's 100 lbs. per inch. Imagine how much force is created in our full length 35-3/4" (908 mm) Door Rails!

CRL Wedge-Lock® Door Rails come completely fabricated and ready-to-install right out of the carton with the End Caps installed. After the rail is installed, the only thing required before hanging the door is to attach the door arm or pivot (not included) to the adjustable door alignment slide already assembled in the Door Rail. The Adjustable Door Alignment System feature allows you to adjust the door 1/8" (3.2 mm) toward or away from the jamb without removing the door. This is standard on both top and bottom rails. NOTE: All Wedge-Lock® Door Rails feature the built-in Jamb Alignment Block, but arms and pivots must be ordered separately to meet job requirements.
