The Sea-Dog Add-A-Snap in black, 2-1/2" size, is a purpose-built solution for boat cover installation and maintenance. Designed for canvas and nylon boat covers, this marine hardware snap extension allows you to easily add length to worn or shrunk material, restoring proper fastening coverage on hard-to-reach areas without requiring full cover replacement.
Constructed from nickel-plated brass with nylon components, the Add-A-Snap is engineered to resist corrosion in marine environments where salt air and moisture accelerate degradation of standard fasteners. The nickel plating provides a protective barrier against oxidation while maintaining secure mechanical engagement with existing snaps. The 2-1/2" dimension specifies the extension length, allowing you to bridge gaps created as cover fabric settles or contracts over seasons of storage and weather exposure. Installation requires no special tools—the snap simply interfaces with your existing cover hardware.
This accessory serves weekend boaters maintaining seasonal covers and serious offshore fishermen who need reliable gear protection year-round. Rather than investing in an entirely new cover when existing material shrinks due to UV exposure or age, the Add-A-Snap extends the functional lifespan of quality canvas and nylon covers. It's particularly valuable for securing covers on boats with complex hull geometry where gaps emerge as materials age, keeping your vessel protected from weather, UV damage, and contaminants.
Compatible with standard boat cover snap systems, this hardware is a cost-effective maintenance solution that belongs in any boater's storage locker alongside cover repair tape and fastener replacements.
