J channel
Alum-A-Pole Corp.

The Auto-"J"-Align is a strip of vinyl with Pro-Trim Tape on part of that strip. It is secured to the back of any "J" channel, leaving a 3/4-inch tight vacancy for the coil stock to be inserted into. The end result is the coil will always align perfectly because the coil is merely butted up against the side of the Pro-Trim tape. The fit is so tight that the "J" channel and bent coil appear as one piece.
