SBS 8" Center Fin for Longboard & SUP - Glass-Filled Nylon Surfboard Fin for Standard US Fin Box - Includes No-Tool Screw & Plate

A potentially great product that needs some tweaking. The issue is that the square nut is sloppy in the fin slot. So lining up the screw with the nut is loads of fun. Haha. Once finished, it appears to be a solid fit.

Fits like a glove, shipped overnight. Ready to try out this board I picked up! Totally happy with the fin. Feels relatively stiff like a normal longboard fin (not cheap and flexy) I like the no-tool fastener. Prevents slipping and damaging board with screwdriver. Good deal.

Works great, easy to install and durable

Fits snug in the fin box. Surprised its a nice sturdy fin for such a low cost. I'm using it in a thruster setup with my board. Should give me the stability I need charging the big waves this winter.

Does the job, good fit, good alternative if you don’t want to pay for a more expensive fiberglass fin

Accidentally lost my iSUP fin on a paddle and reeeeeeally didn't want to spend $40 and an extra $20 for shipping on the branded fin. I was delighted to find this, it's a super simple swap for my ISLE Pioneer 2 Inflatable Paddle Board and pretty affordable. I actually ended up buying a few different sizes from this company to tailor to different paddling environments. I bought one for the deeper lakes for more stability and one for shallower lakes/ponds.

I love that the mounting screw (metric) is a thumb screw and not under the hook! They work great. My only complaint is that there's waaaaay too much packaging. Stop it! Anyway, I highly recommend them for the common surfbag like me. The pros get all their stuff for free so don't buy into a brand just because King Slater, not a dig, he deserves everything and much respect but you aren't doing what he's done. So save some dough, I bought a couple. Cheers and stay stoked!

I lost my fin while traveling in remote West Virginia and definitely nowhere to purchase a replacement in the area. Immediately ordered this fin and had it sent overnight to my hotel. Was so grateful the fin was in stock and shipped on time. Price is very good and could not believe the quality of the fin and the care taken in packaging it. Everything about the fin and mounting screw and plate are perfect. Very high quality and luster to the fin material. Thank you and hope to purchase from this vendor again in the future. Thank you for saving my SUP.

Arrived as expected. Thanks.
