The ROYAL BUILDING PRODUCTS 35-1624 is a 6-inch siding gasket cap designed to provide a finished, weather-resistant seal at siding penetrations and terminations. This component is used in exterior cladding applications to cover and protect the joint between siding panels and adjacent surfaces, preventing moisture intrusion and air infiltration. Installation is typically performed by siding contractors, general contractors, or experienced carpenters as part of a new installation or remediation project.
This gasket cap is suited for residential and light commercial exterior siding applications where a clean termination point is required. It is commonly installed at wall penetrations, window and door surrounds, or at transitions between siding runs. The 6-inch profile is sized to match standard 6-inch siding panels, making it a direct-fit component in compatible siding systems.
Designed as an OEM-style replacement or new-installation component for standard 6-inch exterior siding systems.
Installation should be performed by a qualified siding contractor or carpenter familiar with exterior cladding systems. Ensure the substrate is clean, dry, and free of debris before fitting the gasket cap. Follow local building codes for exterior weather barrier and moisture management requirements. Do not compress the gasket beyond its designed range, as this may reduce sealing effectiveness.
