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

Flannery’s Siding Outside Corner for Fiberon® Cladding is a trim that creates a sharp and crisp corner where siding is installed on walls that meet at a 90° inside corner joint. The Inside Corner trim creates a solid and clean corner for the siding system which would normally require the two pieces of siding to be laid together at an inside corner.
