Hey surfers! If you're working on your longboard and need replacement fin boxes, this 2-pack has got you covered. These black plastic fin boxes measure 10 inches long, 0.35 inches wide, and 0.6 inches deep - perfect standard size for most longboard applications. The plastic construction is durable enough to handle ocean conditions but still easy to work with if you're doing repairs or custom builds. Having two in the pack is super convenient - you can replace multiple boxes or keep a spare for future projects. The installation is straightforward if you have basic board repair skills, though you might want to watch a few tutorials if you're new to this. The black color blends well with most board designs and won't stand out awkwardly. Whether you're fixing damage from a previous session or building a custom board from scratch, these fin boxes provide that reliable foundation you need. They're compatible with standard longboard fins, so you won't have trouble finding fins that fit. The quality is solid for the price - not premium professional grade, but definitely reliable for most recreational surfers. Keep your board in good shape and ensure your fins stay securely in place with these replacement boxes. Perfect for DIY repairs that save you money compared to taking your board to a shop every time!
