Trim, corner molding, gutter rails, and awning rails contribute to your RV’s structural integrity and assist in preventing water damage. Flat aluminum extrusions are applied along seams and transitions to provide a smooth, finished appearance. Corner molding, with its L-shape, is designed to fortify these junctions but also seals gaps between adjoining panels, enhancing structural integrity and weather resistance. Gutter rails, designed as miniature gutters, play a role in water management, directing rainwater away from the RV's sides, thus preventing water streaks and potential water damage. Awning rails feature a channel for securely attaching and holding the awning fabric, allowing for smooth extension and retraction.
