J Channels
Aluminum J channel is a J-shaped profile used to retain and finish panel edges in siding, trim, and cabinetry installation. Stocked in 6063-T5 alloy, in mill finish, clear anodized, or black anodized, across standard 4 ft, 6 ft, 8 ft, and 12 ft lengths, with multiple leg depths available to match panel thickness. The open channel captures a panel edge from one side, making it a common choice at the perimeter of a panel run where the far edge is already secured by another method, and it's stocked in sizes to match a range of panel materials and thicknesses.
