Installaton Guide
Allow for 1/16" expansion on both sides of the threshold.
Use a counter sink so screw fits flush with the surface of the threshold. DON'T drill too deep.
Use tripolymer, or equivalent, sealant for installing threshold.
Use stainless screws. For a ¼” wide threshold use a #12 x 1”; for a ½” use a #12 X 1 ½”; for a ¾” use a #12 x 2” flat head, so they fit flush with the surface of the threshold.
Any threshold over 7" in width should be doubled screwed on both sides.
Screw placement should be 2" in from both ends, then every 8".
4-7" Wide
8-18" Wide
