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

The Sea-Dog Nylon Top Cap in Black, 3/4", is a UV-stabilized injection-molded fitting engineered for Bimini top systems and marine canvas applications. Designed to connect to 3/4" or 7/8" round tubing and 1" square tubing, this top cap serves as both an attachment point and pivot anchor in frame-mounted canopy assemblies. The 1/4" pin size accommodates standard Bimini hardware and fastening systems used across recreational and commercial marine platforms.

Construction from UV-stabilized nylon provides weather resistance in saltwater and extended sun exposure environments, critical for marine hardware that faces constant UV degradation. The injection-molded design ensures consistent wall thickness and dimensional tolerance, essential for reliable pivot action under the stress loads generated by canvas tension and wind loading. At 0.1 lbs with compact 2 x 2 x 6 inch profile, the fitting integrates seamlessly into existing frame assemblies without adding bulk or requiring structural reinforcement. The black finish offers aesthetic consistency across modern boat designs and reduces glare in high-sun conditions.

This top cap is ideal for boat owners, marine repair technicians, and marine fabricators seeking OEM-quality Bimini top components. It replaces or upgrades worn canvas frame hardware on center console fishing boats, center pillar canopies, T-top installations, and other canvas support systems. The 3/4" sizing fits standard mid-size frame configurations; verify your existing tubing diameter and pin hole specification before purchase to ensure compatibility with your frame assembly.

Sea-Dog is a recognized manufacturer of marine hardware with specialized expertise in canvas and frame systems for recreational and commercial vessels. This part number (273110-1) is the industry standard replacement for Bimini installations, ensuring drop-in compatibility with existing documentation and service records. Stock the 3/4" Black nylon top cap as a maintenance spare or complete a frame rebuild with confidence in verified fit.
