KINTLE 58182 Grill Rail Mount Bracket — 2 Pack

The KINTLE 58182 rail mount brackets are designed as replacement parts compatible with Kuuma grills and many RV or boat setups. The package includes two brackets and all shown accessories. Suitable for 7/8″ to 1-1/4″ round rails, as well as 1-1/4″ square rails. This solution emphasizes versatility for various railing configurations, enabling secure mounting and minimizing movement during use.
Pontoon Boat Grill Adjustable Railing Mount

This 1-1/4″ square rail mount offers adjustable positioning with 360-degree rotation to keep the grill oriented for a flat cooking surface. Made from 100% stainless steel, it is designed for durability in marine environments. The bracket is compatible with most pontoons and ensures easy access to grilling while you cruise or anchor.
58182 Stow N’ Go Grill Rail Mount Bracket

The Stow N’ Go rail mount is designed for Kuuma grills, supporting both round and square railings from 7/8″ to 1-1/4″ and 1-1/4″ square. Constructed from high-quality aluminum with an anodized finish, these mounts resist corrosion. The knurled interface and bolt design help prevent slippage after installation, while allowing the grill to hang outside the rail to protect decks from spills.
58182 Stow N’ Go Kuuma Variant — With Attachment

This rail mount is compatible with Kuuma grills and supports mounting on both 7/8″ – 1-1/4″ round rails and 1-1/4″ square rails. The attachment design enhances stability, making it suitable for RVs and boats where vibrations or movement could otherwise affect grill position. Aluminum construction balances strength and weight for marine or camper use.
Brocraft Pontoon Grill Bracket

Brocraft’s pontoon grill bracket uses marine-grade T6 aluminum with CNC processing for durability in saltwater environments. It supports 7/8″ to 1-1/2″ round rails and 1-1/4″ square rails. The design allows grilling slightly outside rail lines to shield fiberglass surfaces from splatter, making cleanup easier and keeping decks protected.
MiDive Umbrella Holder With Rail Clamp

While not a grill rail mount, the MiDive heavy-duty umbrella holder complements deck setups by providing a sturdy clamp-on solution that maximizes railing space. Constructed from metal with a black powder coating, it offers stability in windy conditions and can help shade grilling areas on decks or rail-mounted configurations.
Buying Guide: Key Considerations For Rail-Mounted Grills
- Rail compatibility: Verify whether the bracket fits round rails (commonly 7/8″ to 1-1/4″) or square rails (often 1-1/4″). Some mounts support both shapes, increasing versatility across boats and RVs.
- Weight and materials: Look for marine-grade aluminum or stainless steel for corrosion resistance and lightweight handling. Anodized finishes add durability against salt air and moisture.
- Mounting security: Knurled interfaces, reinforced bolts, and locking mechanisms reduce the risk of slippage during cooking, fuel pressure changes, or vessel movement.
- Adjustability: Rotational and tilt capabilities help maintain level grilling surfaces on uneven decks or moving boats, improving heat distribution and cooking consistency.
- Compatibility with grills: Confirm that the bracket is specifically rated for use with Kuuma or similar grills if you own a particular model, to ensure a proper fit and load rating.
- Protection of surfaces: Some mounts position the grill outside the rail to minimize splatter on fiberglass or wood decks, which can simplify cleanup and prevent staining.
- Portability and storage: Consider whether the mount is fixed or foldable. Foldable designs save space when not in use, particularly on smaller decks or boats.
- Maintenance: Check for easy cleaning options and resistance to corrosion, rust, and pitting. Rinse after exposure to saltwater or chlorine.
- Installation complexity: Some assemblies require minimal tools, while others involve multiple fasteners. A straightforward design reduces installation time and mistakes.
When choosing a deck rail mounted grill system, balance versatility, durability, and grill compatibility with your specific boating or RV setup. Consider how often you grill on stable decks versus moving vessels, and select a mount that offers secure attachment, adequate load support, and ease of maintenance.
