CRL Black Bronze Anodized 4" Tapered Door Rail Without Lock for 3/4" Glass - 35-3/4" Length - DR4TDU34S
An innovative new 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.), 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 pounds) in our nine inch (228.6 millimeter) Corner Rail. That's 100 pounds per inch. Imagine how much force is created in our full length Door Rails! The Wedge-Lock Glass Securing System gives you more than a secure attachment to the glass. It provides the fastest installation time of any door rail system offered to the industry. Experienced installers can have a door prepared for installation in less than ten minutes. 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 inch (3.2 millimeter) toward or away from the jamb without removing the door. This is standard on both top and bottom rails. After the door is installed all you need do to adjust the door is to remove the End Cap. This will reveal three socket head cap bolts. The center bolt is the securing bolt used to lock the adjustable slide in position. The two outer bolts are used to adjust the slide 1/8 inch (3.2 millimeter) in or out. The low profile of the adjustable slide allows the pivots with slotted grooves to be moved to a position other than the American Standard Setback of 2-3/4 inches (69.8 millimeter). This means we can fabricate them for vertically out-of-square openings. Other reasons to choose CRL Wedge-Lock Door Rail System: Models are available to accept 3/8, 1/2, or 3/4 inch (10, 12 or 19 millimeter) glass; a rigid single component housing that will not shift and fall out of adjustment over time because it is not made up of two halves; the internal components do not require removal before installation; the glass securing pads are designed for longevity in extreme environments. 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. CRL Wedge-Lock Door Rails come in several standard finishes, and can be quoted in custom finishes and widths upon request.
