Products / Dek-Cap Standing Seam End Cap Flashing

Dek-Cap is ITW Buildex's universal end cap flashing for standing-seam metal roof panels, used where a panel ends at metal curbs, skylights, ridges and jobsite retrofits. The 2026 product catalog describes a thermal elastomer body (continuous service from -40 to +250 degrees F) on a flexible, corrosion-resistant aluminum base that conforms to most standing-seam panels, a pre-formed panel profile usable on left- and right-handed seams, dual underside sealing ridges, an expansion notch and marked fastening points; it is installed with polyurethane sealant under the aluminum edging and fastened with Buildex Scots self-drilling screws. It is sold ten to a box as part 4146910.
