Plastic Bimini Base Ø22 mm – Horizontal Mount (Grey/Black)

This plastic bimini base for 22 mm tubing is an essential accessory for installing a folding boat canopy (bimini top). Constructed from high-quality engineering plastic (nylon), it offers excellent strength and weather resistance. The material is impervious to saltwater and sun exposure – it won’t corrode or degrade, ensuring the part has a long service life even when constantly exposed to UV rays.

The base is designed for horizontal surface mounting, meaning it attaches to flat areas such as the deck, cabin roof, or the top of the gunwale. Its compact dimensions (~55 mm length, 25 mm width) allow it to be installed unobtrusively, without taking up much space or detracting from the boat’s aesthetics. Installation is done using two screws (not included); using stainless steel screws is recommended for maximum durability in the marine environment. Once mounted, the base sits flush and holds firmly, capable of withstanding the stresses from boat motion and wind loading on the canopy.

The top part of the base features a hinge with a vertical pin onto which the bimini’s frame end (eye end fitting) is attached. This design allows the canopy frame to pivot freely up and down. When the bimini is raised, the hinge keeps it securely in position, and when you need to lower or fold the top – for example, when trailering the boat or facing strong headwinds – the frame can swing downward, with the hinged connection preventing any twisting or breakage. This makes operating the bimini very convenient: you can quickly lift it up to provide shade, and just as quickly fold it down out of the way when needed.

Compatibility: The base is compatible with all standard bimini tops that use 22 mm (7/8") diameter tubing – a very common size for small and medium boats, RIBs, and yachts. The set includes the hinge piece with pin; the tubular frame’s end fitting (“jaw” or “eye”) slips into it and is secured by the pin. If you are replacing old or broken deck hinges, ensure your frame tube diameter is 22 mm for the best fit.

Color options: This model comes in two colors – grey or black. The grey base blends nicely with light-colored gelcoat or aluminum surfaces, while the black version is preferred for boats with dark trim or if you already have other black plastic fixtures. Both color variants are UV-stabilized and will not fade or chalk when exposed to sun.

Using this plastic bimini deck hinge makes the installation and removal of your canopy much easier. In practice, these bases are often used in pairs – one for each side of the bimini frame (port and starboard). It’s recommended to position the bases symmetrically during installation so that the canopy tension is even. With this affordable and reliable solution, you’ll ensure your sunshade is mounted securely, without adding unnecessary weight or corrosion-prone components to your boat.
