Genuine Edson marine hardware is always worth saving, especially as replacement steering, pedestal, radar pole, and deck-mounting parts continue to get harder and more expensive to source. This listing is for an Edson B-480 base flange clamp mount, also identified in current Edson retail references as part number 978-23-35B, designed as a base flange mount for a 2-3/8 inch mast. Edson describes this flange as part of a two-flange through-deck mounting system: the base flange has a shoulder that supports the bottom of the 2-3/8 inch radar mast, while the matching 978-23-35D deck flange is used separately to allow the mast to pass through and be secured in place. Edson recommends using large washers or backing plates when securing these flanges to deck or hull structures. Retail references show this part at about $131-$138 new, and secondary marine sellers have listed open-box examples around $90, making a clean used-good genuine Edson part a strong value in today’s higher-demand marine parts market. Condition is used-good with normal cosmetic wear from prior handling/installation, possible surface marks, and typical marine hardware patina; inspect photos for exact condition and included hardware. Great for sailboat steering pedestal projects, Edson radar pole installations, marine mast mounting repairs, cockpit electronics upgrades, and hard-to-find OEM Edson replacement parts. Buyer should verify fitment, bolt pattern, and compatibility with their existing Edson pedestal, mast, or deck flange system before purchase. #MarineParts #Edson #FlangeClamp #BoatParts
