Siding H-Mold

Trim Purpose

Specs, MSDS, and LEED Information for Flannery Trims & Products

Flannery’s Siding H-Mold is a trim for siding that creates a “flat-face” reveal over two adjoining siding pieces. The Siding H-Mold is an important part of siding products that might require a relief to the expansion and contraction of the siding. The Siding H-Mold fits neatly in between two panels and comes with a 1” face flange, which allows the installer to slide the siding in behind the flange and cover the unfinished edge of the panel.
