Deep U-Channel is for securing fixed panels of glass to the wall, ceiling or floor. Widths suitable for 3/8" (10 mm) thick glass are available, and are individually wrapped to protect the finish. This 3/4" (19 mm) high profile Deep U-Channel can be used as the top channel in installations where the glass must be inserted into the top, then lowered into the 3/8" (10 mm) tall Regular U-Channel used at the bottom of the enclosure.
