CertainTeed J Channel

CertainTeed's Vinyl J Channel was constructed to be used as a universal siding and soffit receiving channel that is designed for use around utility openings, under eaves, and more. There are a few options of J Channel sizes available, including the 1/2in., 3/4in., and 1in. sizes. The 3/4 in. size J Channel is the basic size, the 1/2 in. J Channel is for smaller soffits or a tighter fit against the material, and the 1/2 in. and 3/4 in. sizes are both recommended for new installations.
