Door Seal Kit Top Bar Trim Instructions for doors smaller than 36" wide
If the top bar is wider than the width of the door slab, a small section will need to be removed from between the screw notches. Measure the width
of the door slab. Subtract this measurement from 36". The difference is the amount that needs to be removed.
On the top bar, mark one side at 1" from the center hole. From this mark, measure
and mark the difference between the top bar and the slab. Using a hack saw, trim
at both markings. You will have one long piece and one short piece that when
placed side-by-side will be the width of the door slab.
1"
Using a 1/8" drill bit, drill a
hole one inch from the end
of the shorter piece that
does not have a hole.
See Step 4 to complete installation.
Care and Maintenance:
As needed, clean rubber bug sweep with non-oily product such as mineral spirits.
