Overview

The TACO Marine F11-0180S-1 is a 90 degree top cap for 7/8 inch outside diameter tubing, used as a side-mount ball and socket fitting on boat canvas and shade hardware. It finishes the end of the tube at a right-angle connection point and uses a set screw fastener, which is useful when the fitting needs to be positioned, serviced, or adjusted without a pop-rivet installation.

This fitting belongs to TACO Marine’s ball and socket top fitting range and is made from polished Type 316L stainless steel with a Delrin insert. The pivot design allows full rotation, helps reduce rattling at the connection, and gives the frame a cleaner range of movement when used with compatible bimini, shade, or canvas support hardware.

Key features

• Fits 7/8 inch outside diameter tubing for common marine canvas and shade frame applications.
• 90 degree side-mount top cap configuration for right-angle tube terminations.
• Set screw fastening allows installation without a pop-rivet on this configuration.
• Polished Type 316L stainless steel construction for exposed marine hardware locations.
• Delrin insert helps the ball and socket connection move smoothly and reduces fitting rattle.
• Patented ball and socket pivot design supports full rotation at the connection point.

Installation and fit

Use this top cap where a 7/8 inch tube needs a 90 degree end fitting for a canvas or shade frame. Before installation, confirm the tube outside diameter and check the mating ball and socket hardware in the existing frame so the fitting matches the rest of the system.

The set screw should be seated against clean tubing and tightened evenly. On boats exposed to vibration, trailering, or repeated folding of a bimini frame, the connection should be checked as part of normal hardware inspection.

Marine use

The polished stainless finish makes this fitting suitable for visible topside locations where hardware appearance matters, such as bimini frames, shade supports, and canvas structures around cockpits or helm areas. It is a practical match for owners replacing a worn fitting or fabricators building a frame that needs a controlled 90 degree tube connection with a smooth pivot point.
