GapCap

Stop deck gaps at the source

As deck boards expand and contract with the seasons, unsightly gaps open up at corners, fascia joints and stair risers — a headache for contractors and homeowners alike. GapCap covers those gaps with a clean, finished cap that installs in minutes and looks like it was always part of the deck.

Sold as a 2-pack.

Two styles: TopCap (walking surface corners) and FasciaCap (fascia boards & stair risers).

Three angles: 90° square corners, 45° mitered corners, 0° straight joints.

Three colors: Grey, Brown, Black — matches composite and treated wood decking.

Installs with standard composite deck screws and includes matching plugs for a screwless finish. Works on new or existing decks.
