WEATHERSTRIPS (MAY NOT BE INCLUDED):

Depending on the size of your door, you may have to cut or trim the weatherstrips (if neces-

sary) to properly fit into the header and jambs.

NOTE:

 If nailing product at 40°F or below, pre-drilling is required.

NOTE:

 Do not permanently attach weatherstrips to the header and jambs at this time.

For the header, align the weatherstrip 1/8” to 1/4” inside the header edge, and temporarily 

secure it to the header with equally spaced nails. Starting at either side of the jamb, fit the 

weatherstrip up tight against the temporarily attached weatherstrip in the header and 1/8” 

to 1/4” inside the jamb edge. Temporarily secure the weatherstrip with equally spaced nails. 

Repeat for other side. This will keep the bottom section from falling out of the opening during 

installation. Equally space nails approximately 12” to 18” apart.
