Sea-Dog Nylon Top Insert - Black - 3/4"

The Sea-Dog Nylon Top Insert in Black – 3/4" is a marine-grade fitting designed to connect seamlessly to round tubing as either a top cap or top insert component. Built for Bimini top systems and canvas frame assemblies, this insert creates a secure attachment point while serving as a pivot junction that allows controlled movement and positioning of canopy structures. Whether you're upgrading an existing marine canvas system or building a custom frame, this nylon insert provides a reliable connection solution for 3/4" round tubing applications.

Manufactured by Sea-Dog, a trusted name in marine hardware, this fitting is engineered from durable nylon material that resists corrosion and UV degradation—critical factors for equipment exposed to saltwater and harsh sunlight. The design incorporates a 1/4" pin size, allowing it to function as a pivot point that enables smooth articulation of Bimini top frames during raising and lowering operations. The compact 2 x 2 x 5-inch profile and lightweight 0.05 lb construction make it easy to install without adding unnecessary bulk or weight to your marine structure.

This fitting is ideal for boat owners, marine technicians, and canvas fabricators who work with 3/4" round tubing or 7/8" round tubing applications, as well as 1" square tubing configurations. Installation requires basic mechanical skills and standard tools, making it accessible for both professional installations and DIY marine projects. The black nylon finish complements most boat aesthetics while maintaining excellent UV and saltwater resistance for long-term reliability in demanding marine environments.
