Typically used in Longboards, Single Fin surfboards, Egg and Bonzer Shapes, and as a Stand Up Paddleboard fin box. You can install a 10.5" centerfin box in a quad fin setup to make it a "Versaplane" where the fin arrangements are endless... This 10.5" Centerfin box is installed after the hotcoat Review: Great design = outstanding product - The question "easy to install?" isn't quite fair, as fin box installs are a pain in the neck. But this fin box is a lot easier to install than the originals. Two features make the SBS box a gem, the ribs on the side of the box and the very thin tabs on top. These make the job much easier and quicker with a lot less sanding. The ribs allow you to place the fiberglass cloth inside the rout rather than over the surface of the box. The tabs that suspend the box above the fin rout are about 1/32". With the extra layer of glass and a thick surface tab eliminated, finish sanding becomes a breeze. Great design = outstanding product. Review: Great product - This fin and box was installed on a 8’ SUP and works great. My grandsons are having a ball. Very solid once installed and the board runs true. Very good product and a lot cheaper than I thought they would be ## Features - The industry standard surfboard center fin box in 10.5" length will fit any single fin known to man. - Typically used in Longboards, Single Fin surfboards, Egg and Bonzer Shapes, and as a Stand Up Paddleboard fin box. - Shaping your board, or fixing a broken fin box, this is the one you need. - Works with all SBS single fins and fin screws such as our No Tool fin screws - We stand behind every product we sell ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071HGNHFC | | Age Range Description | All | | Best Sellers Rank | #286,594 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #142 in Surfing Fins | | Brand | Santa Barbara Surfing | | Brand Name | Santa Barbara Surfing | | Color | black | | Customer Reviews | 4.6 out of 5 stars 160 Reviews | | Item Weight | 16 ounces | | Manufacturer | Santa Barbara Surfing | | Manufacturer Part Number | SBS-125 | | Material | Polyurethane, Fiberglass, Metal | | Material Type | Polyurethane, Fiberglass, Metal | | Model Number | SBS-125 | | Size | 10.5" | | Skill Level | All | | Sport | Surfing, Standup Paddleboarding | | Sport Type | Surfing, Standup Paddleboarding | ## Product Details - **Brand:** Santa Barbara Surfing - **Color:** black - **Item Weight:** 1 Pounds - **Material:** Polyurethane, Fiberglass, Metal - **Size:** 10.5" ## Images ![SBS Surfboard Single Fin Box 10.5 Inch - Image 1](https://m.media-amazon.com/images/I/81eDuFem-iL.jpg) ## Questions & Answers **Q: I have a progessive sup looks like opening is 10.5 x 1.25 in abs . how is it installed and will it fit?** A: It installs exactly how a normal single fin would install to any single fin box, and your FCS center fin will go in it as it would into a pair of FCS fin tabs (using fcs hex screws to secure). I will admit, it is a tight fit for FCS Brand fins to get into, I sanded the two tabs a little bit on a cheap FCS Center fin to make it a little easier to get into the adapter. True Ames fins fit in a little easier. However the adapter fits perfectly into any Single fin box (U.S. or Aussie). Worth the purchase price to experiment with **Q: Is this product durable enough to suppot a home made foil mast?** A: Sorry I am not sure what kind of loads a mast puts on a fin box but if other fin boxes can handle it, so can ours. **Q: can you tell me the width of the opening of the fin box?** A: The slot that accepts the base of the fin is 1/4 inch wide. The center slot that accepts the metal pin is 9/16 inch. Not sure if that is what you mean by "opening". The fin box is an industry standard for almost all fins designed for a single fin surfboard. **Q: Is it installed similiar to a future center fin box, before laminating or after hot coat?** A: I installed mine after the hot coat. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great design = outstanding product *by S***. on September 12, 2023* The question "easy to install?" isn't quite fair, as fin box installs are a pain in the neck.
