J-channel member for siding

摘要

J-channel member comprises a relatively rigid plastic back leg and channel bottom wall, with spaced apart slits along the length of the back leg to permit bending of the bottom wall around a radiused opening, and a relatively flexible plastic front leg which permits stretching of the front leg during such bending of the bottom wall while leaving the front leg intact. At the outer end of the front leg is an inturned annular lip which is urged radially inwardly into engagement with the trimmed ends of vinyl or aluminum siding received in the channel to help hold the siding down and enhance the overall appearance of the joint.
