Sea-Dog Nylon Top Cap - White - 7/8"

The Sea-Dog Nylon Top Cap in white, 7/8" size, is a precision-engineered fitting designed to cap or insert into round and square tubing systems commonly found in marine and industrial applications. Constructed from UV-stabilized injection-molded nylon, this top cap delivers reliable performance in harsh outdoor environments where exposure to direct sunlight and saltwater spray would degrade lesser materials. The 1/4" pin size accommodates standard pivot hardware, making integration into existing Bimini top systems and similar frameworks straightforward.

This fitting accepts 3/4" or 7/8" round tubing or 1" square tubing, providing versatility across multiple frame geometries. The UV-stabilized nylon composition resists degradation from extended sun exposure—a critical consideration for overhead canopy structures and outdoor equipment frames. The white finish offers visibility and aesthetic continuity in marine deck setups. Stainless tube wall thickness of 0.049" ensures adequate structural support for load-bearing applications. Whether serving as a top cap for closed-end tubing or a top insert for through-fitting configurations, this component functions as both a protective closure and a structural pivot point within the assembly.

Operators, marine technicians, and equipment maintenance professionals rely on Sea-Dog fittings for Bimini top systems, canopy frames, and outdoor structural assemblies. The nylon construction is lightweight yet durable, reducing overall frame weight while eliminating corrosion concerns associated with metal caps in salt-air environments. This 7/8" white cap is ideal for retrofit work, replacement installations, or new-build frameworks requiring UV-resistant, corrosion-proof hardware. Part number 273101-1 (UPC 035514273015) ensures compatibility verification and streamlined reordering across equipment fleets and maintenance inventories.
