Yes, absolutely. They are made from 316 marine-grade stainless steel, which is specifically formulated to resist the corrosive effects of saltwater. This is the standard for high-quality yacht and boat hardware.
No, screws are not included with the purchase. You should select marine-grade 316 stainless steel screws to match the base. For best results, use a silicone sealant or marine caulk beneath the base to ensure a fully watertight installation against your boat's deck.
The main difference is in the base footprint. The "Front/Center" (standard stanchion) has a slightly shorter, narrower base, making it suitable for tighter spaces like the bow or midship. The "Front/Rear" (aft) has a wider, longer base for increased stability on the transom or stern. Always measure your available deck space before ordering.
Yes, they are designed to fit standard 1-inch OD tubing perfectly. The inner diameter of the ring is 25.5mm, which provides a snug fit for 25.4mm tubing. You may need to lightly sand or file the inside of the tube if it is oversized for a smooth installation.
Silica sol investment casting is a premium manufacturing process that uses a fine ceramic mold to create parts with exceptional surface finish and dimensional accuracy. It results in a denser, smoother, and stronger final product with almost no porosity, which means better resistance to cracking and cleaner, more beautiful looks compared to sand casting.
