Corner Blocks

Corner block

Install 1/2" J-channel as a starter. Measure and cut the side lineals to the exact size of the window or door opening.

Cut the top and bottom lineals 1/4" longer than the window.

Using vinyl snips, make two 1" long cuts in the pocket areas on both sides of each lineal. These cuts allow the lineals to connect with the corner block and help provide proper drainage.

NOTE: It may be helpful to hold off securing the lineals until the corner block is in place.

Position the corner block by inserting the top lineal into the corner block’s receiving area—making sure the lineal’s pocket is inside that of the corner block.

Position the vertical (side) lineal into the corner block by inserting the pocket of the corner cover into the pocket of the lineal.

This will ensure proper drainage.
