CertainTeed Vinyl Siding Installation Guide

Measure the side casing and add 7". Use a triangle to create a 45˚

angle or measure 3-1/2" in from the edge of the part. Use snips or

a miter saw to remove this portion.

Flip the part over and remove the locking leg as shown.

This should be done to both ends.

Snap the lineal over the J-channel as shown. Use the same

measurements for both sides.

Corner blocks

Install J-channel around the perimeter of the window opening.

J-channel should be the same length as the casing.

Install corner blocks on all 4 corners as shown. Leave blocks loose

until the lineals are installed.

Cut the lineals the same length as the window casing.

Start with one end and angle a lineal into the corner block and

snap it over the J-channel.

Continue installing lineals around the window.

Crown molding

Crown molding will ﬁt over the top of the lineal system.

Install J-channel and lineals around window casing.

Measure the top lineal and add 2-1/2". This will be the crown

molding length.

Insert crown molding cap into the crown molding and trace the

shape. Trim off the marked line.

The crown molding requires a tab 2" long—cut from the pocket

receiver as shown.

Cut the crown molding cap in half and apply the halves with a

bead of caulk.

Insert the crown molding into the top of the lineal as shown.
