This plastic rail connector provides a quick and reliable way to join handrails and grab rails on boats and yachts. Designed for Ø22 mm tubing, it firmly clamps around the tubes, creating a stable right-angle connection – particularly useful when constructing side railings or adding extra handholds. The design is a two-piece assembly – an upper and lower bracket that tighten together with stainless steel screws. This means you can install it without any drilling or welding: simply position the clamp at the desired height on an existing tube (such as a vertical stanchion) and insert the horizontal rail tube into the fitting – once bolted down, the connection is solid and immovable.
The connector is made from high-strength nylon (technopolymer) that withstands UV rays, saltwater, and temperature swings. This ensures the part will last for years even under continuous outdoor exposure. The clamp won’t rust or seize up, unlike metal alternatives, and requires virtually no maintenance. It provides a fixed 90° join, holding the attached tube securely at a perpendicular angle, so your rail stays aligned and won’t sag or loosen over time.
Applications and recommendations:
- Installing horizontal guardrails/handrails on RIBs or small boats that lack factory-fitted rails. This connector allows you to add additional safety grab rails for passengers with ease.
- Bimini top frames: Use the clamp to join support poles of a bimini top or canopy to an existing rail or console tubing. When you need to fold down or remove the frame, the clamps can be quickly loosened and detached.
- Adding auxiliary rails for accessories – e.g., mounting fishing rod holders, cup holders, or other add-ons onto existing boat tubing.
- Ideal for repairs or retrofits: if an original rail joint broke or corroded, this product can replace it without complex work, restoring the railing’s integrity.
The Eval 00665 connector comes in two colors – black or white – giving you flexibility to choose what best matches your vessel’s decor (whether you have black plastic bases or white fittings on board). Whether you are outfitting a new boat or upgrading an older one, this plastic Ø22 mm rail clamp helps you install and modify railings and frame systems quickly, securely, and professionally.
