Sea-Dog Line Tank Hold Down/Installation Kits
Sea-Dog Line Poly Gas Tank Strap Kits: Marine-Grade Security for Your Fuel Tank
When a portable fuel tank shifts underway, the consequences range from annoying to genuinely dangerous. A properly secured tank is one of the most fundamental elements of safe boating — and it's a job that Sea-Dog Line has long taken seriously. As a brand with roots stretching back to the early 1920s and over a century of marine hardware experience, Sea-Dog brings that same legacy of durability and function to its Tank Hold Down & Installation Kits.
The Sea-Dog Poly Gas Tank Strap Kit
Sea-Dog Line's entry in this category is its Poly Gas Tank Strap Kit (Part No. 359995-1), a straightforward but well-engineered solution for securing portable fuel tanks aboard recreational vessels. The kit features a 1" x 6' nylon webbing strap designed for use in securing a portable gas tank. The complete kit includes a nylon webbing strap with a 304 stainless steel buckle, two 304 stainless steel footman's loops, and four #10 FH fasteners — giving boaters everything they need to mount the strap securely to the hull or deck structure without sourcing additional hardware.
The quick-release buckle design is a practical feature that makes routine tank removal and reinstallation fast and tool-free, while the nylon webbing construction resists moisture and the UV exposure that degrades lesser materials over time. Many Sea-Dog products use materials such as marine-grade stainless steel, brass, or UV-resistant polymers to support long-term durability in marine conditions.
Why Sea-Dog Line Stands Out in This Category
Sea-Dog Line Corporation is one of the most recognized and trusted brands in the marine industry, and for over 90 years has supplied boat builders and owners with thousands of high-quality components designed to withstand the harsh conditions of the sea. That heritage translates directly into a tank strap kit that doesn't cut corners — the choice of 304 stainless steel hardware means the buckle and footman's loops won't corrode away on a saltwater vessel, and the tested nylon webbing holds its integrity season after season.
Sea-Dog is proud to have an ABYC Certified Marine Technician on board to aid with any technical and installation issues — a resource that reflects the brand's commitment to getting installations done correctly and safely, not just quickly. Many installers look for components that align with ABYC standards for safety-minded installs, and Sea-Dog's internal expertise supports exactly that kind of confidence.
Choosing the Right Tank Hold Down Solution
A marine fuel tank hold down kit is a set of components used to securely hold the fuel tank in place on a boat, typically including straps, brackets, or other hardware that prevent the tank from shifting or moving while the boat is in operation. A fuel tank that is not properly secured can shift or move underway, which can lead to problems such as fuel leaks or spills — and a hold down kit helps to prevent these problems by securely holding the fuel tank in place.
For boaters running a portable tank in a fishing boat, aluminum skiff, or small runabout, Sea-Dog's Poly Gas Tank Strap Kit delivers a complete, ready-to-install solution backed by a brand that has served the marine industry for generations.
