This screw with washer is designed for fin installation in the US-BOX system used in Gladiator SUP boards (ONE, Origin, Pro and Elite ranges). It is a small but essential component responsible for secure and stable fin attachment.

The screw allows you to slide the fin into the US-BOX track and precisely adjust its position. By moving the fin forward or backward, you can fine-tune the board’s tracking and maneuverability depending on water conditions and paddling style.

Made from durable, water-resistant materials, the screw and washer provide solid pressure and reliable hold inside the fin box. It’s a practical spare part worth keeping in your kit, especially if you frequently remove or change fins.
