Product Details

The Sea-Dog Line 273580-1 is a black nylon square tube top insert designed for use with 1-inch square tubing in Bimini top systems. Constructed from UV-stabilized injection-molded nylon, this fitting is built to withstand prolonged sun and weather exposure in marine environments.

This top fitting serves a dual purpose: it creates a secure attachment point at the end of the square tube and functions as a pivot point within a Bimini top assembly, allowing for smooth folding and adjustment of the canopy frame.

Key Features:

  • UV-stabilized injection-molded nylon construction for long-lasting durability
  • Designed for 1-inch square tubing
  • 1/4-inch pin size for secure attachment
  • Functions as both an attachment point and pivot point in Bimini top systems
  • Black finish for a clean, classic marine look
  • Lightweight and corrosion-resistant — ideal for saltwater use

The Sea-Dog Line 273580-1 top insert is an essential component for building or repairing a Bimini top frame, ensuring reliable operation and a professional finish.
