Magma T10-585 Dual Horizontal Round Rail Mount - Oversize 1-1/8 in. Or 1-1/4 in. Rails

The Magma T10-585 is a dual horizontal round rail mount built for boaters who need a strong, no-tools mounting point for Magma grills and tables on oversize round rails. It is designed to fit rails measuring 1-1/8 inches (28.6 mm) or 1-1/4 inches (31.8 mm) in diameter, making it a fit for larger stern and side rails found on many boats.

What sets this mount apart is its pivoting design, which lets it attach not only to straight sections of rail but also to curved rails or across the corner of a stern rail, giving installers flexibility in tight or angled spaces. Construction is 304 stainless steel paired with 356 hard anodized aluminum, a combination chosen for strength and rigidity so the mount will not slip once clamped in place. When the grill or table is not in use, the mount detaches instantly without any tools, allowing for compact storage and leaving no loose hardware attached to the rail. This tool-free release is a key convenience feature for boaters who regularly stow their cooking or dining accessories between uses.
