The CRL Wedge-Lock® Door Rail System is an innovative glass entrance solution engineered for secure, fast installation of monolithic tempered glass doors. The exclusive Wedge-Lock® design uses two glass-retaining aluminum extrusions compressed by a flat stainless steel bar and socket head cap bolts. The angled extrusions and wedge action create exceptional clamping force—more than 900 lbs. in our 9" (228.6 mm) corner rail—providing industry-leading glass retention for 41" door rails and full-length 35-3/4" rails.

Key differentiators:

• Fast installation: experienced installers can prepare a door in under 10 minutes
• Adjustable Door Alignment System: ±1/8" (3.2 mm) adjustment toward/away from jamb without door removal, standard on top and bottom rails
• Rigid single-component housing that resists shift or loss of adjustment over time
• Internal components remain in place during installation—no disassembly required
• Durable glass securing pads designed for longevity in extreme environments
• Built-in jamb alignment block (arms and pivots ordered separately)

How it ships and installs:

• Comes completely fabricated with end caps installed; pivot attachment hardware not included
• After rail installation, attach the door arm or pivot to the preassembled adjustable alignment slide
• End cap removal exposes three socket head cap bolts for final alignment and locking

Ordering notes:

• All door rails include the standard Kwik-Adjust™ pivot alignment system; closer arms and floor/overhead pivots must be ordered separately
• Models with locks ship with the lock mechanism installed; specify keyed cylinders or thumbturns as needed
• Specify door rail length (including end caps) when ordering custom lengths

Product height: 4-1/16” (103 mm)

Product warning: Comes standard with jamb alignment block. Arms and pivots must be ordered separately to meet job requirements.
