CRL Dry Glaze U-Channel offers the installer many benefits. It eliminates the need for messy silicone between the glass and metal, dramatically reducing installation time. If the glass is ever scratched or damaged it can be removed without the need to cut out the sealant. The extruded aluminum channel is wrapped in a protective poly sleeve with two pieces of clear vinyl to secure 5/16" (8 mm) thick glass. The Flexible Vinyl goes on the interior of the shower, while the Rigid Leg Vinyl "rolls in" on the exterior side. Matching finish End Caps adhere to channel ends, and must be ordered separately. NOTE: Not designed for "Lift and Drop" applications. SPECIFICATIONS: Materials: 6463-T5 Extruded Aluminum, Rigid Clear Vinyl, and Flexible Clear Vinyl Includes: 95" (2.41 m) Lengths of Channel, Rigid Vinyl, and Flexible Center Vinyl
