Need a solid, rust-proof fitting for your boat's handrail? This Yaegarden 90-degree base is exactly that. It's made from super durable 316 stainless steel, which is the good stuff for saltwater use – it resists corrosion and won't rust on you. The base is round, about 65.6mm (2.58 inches) across, and 42mm (1.65 inches) tall. The hole is for a 7/8 inch (22mm) inside diameter tube, and the hole-to-hole distance is 37.2mm (1.46 inches). It's been hand-polished to a really nice mirror finish, so it looks sharp and reflects clearly – no scratches or dull spots. Perfect for installing or replacing handrails on all sorts of boats: yachts, fiberglass boats, inflatable boats, even for awning frames. Super straightforward to use. Just a heads-up, since it's mirror polished, the color in photos might look a tiny bit different in real life, and manual measuring can have a 1-3cm variance. But if you're not 100% happy, they offer a 3-month money-back or replacement guarantee, so you can buy with confidence. Get your boat looking shipshape!
