Sea-Dog Gate Latch

The Sea-Dog Gate Latch is a heavy-duty fastening solution engineered for marine and industrial applications requiring corrosion-resistant hardware. Built from investment-cast 316 stainless steel, this gate latch delivers superior durability in saltwater environments and harsh outdoor conditions where standard steel would degrade rapidly. Operators managing waterfront facilities, pontoon boats, and coastal infrastructure depend on this latch for secure, long-term performance without maintenance-intensive rust prevention.

Designed specifically for 1-1/4-inch square tubing, the Sea-Dog gate latch accommodates standard structural framing commonly found in pontoon gates and marine railing systems. The 316 stainless steel construction provides superior corrosion resistance compared to 304 stainless or painted alternatives—critical when continuous salt spray exposure is a concern. Installation requires a single 1/4-inch thru-bolt (sold separately), allowing straightforward retrofit into existing gate assemblies. The compact footprint (4 x 1 x 6 inches) and minimal weight (0.45 lbs) ensure the latch does not overload frame structures or complicate mounting procedures.

This product serves facility managers, boat owners, and construction professionals who cannot tolerate gate failure or corrosion-related maintenance cycles. Whether securing pontoon access gates, securing dock perimeter equipment, or controlling personnel access at waterfront operations, the Sea-Dog latch provides fail-safe latching without the degradation typical of budget hardware. The stainless steel investment-cast design means no coating to chip or peel—protection is inherent to the material itself, ensuring decades of reliable service in demanding marine environments.
