Our innovative glass entrance solution, the CRL Wedge-Lock® Door Rail System, uses the exclusive Wedge-Lock® Securing System (U.S., Canadian and European patents) to clamp glass securely via two glass-retaining aluminum extrusions and a flat stainless steel wedge bar. As the bar is tightened with socket head cap bolts, angled extrusions engage an internal wedge groove to create extremely high holding force (900+ lbs. in the 9" corner rail), providing superior glass retention for commercial glass doors and storefronts.

Key features and benefits
• Fast installation—experienced installers can prepare a door in under ten minutes using the Wedge-Lock® door rail for 1/2" tempered glass.
• Fully fabricated, ready-to-install rails ship with end caps installed.
• Adjustable Door Alignment Slide (standard top and bottom) allows 1/8" (3.2 mm) in/out adjustment without removing the door—adjust via accessible socket head cap bolts after removing the end cap.
• Rigid single‑component housing resists shifting or loss of adjustment over time (unlike two‑piece housings).
• Internal components remain in place during installation; no disassembly required.
• Glass securing pads designed for longevity in extreme environments.
• Models available to accept 3/8"–3/4" glass for versatile commercial and storefront applications.

Notes
• Actual product height: 4-1/16" (103 mm).
