The trim stop package consists of ¾" x ¾" Solid PVC no maintenance trim.
Insert frame is held in place by being installed between the exterior and interior trim.
Screen+Plus inserts should not be attached to posts but allowed to "float" between trim stops. They are supplied long for final cutting by the installer to ensure a tight fit.
Total of seven pieces supplied for each insert, three for the exterior and four for the interior.
Do not install trim at bottom on exterior as it could trap water.
