FIN GEAR track system is made of high grade aluminum and is attached to boats or products with stainless steel screws. Mounts and accessories easily slide into our track system and out. We also have locking pins that are provided to prevent mounts from sliding out for your protection and security. All FIN GEAR mounts are secured down with thumbscrews that are tightened into the track. Our track system comes in many lengths, 6” , 12” , 18” , 24” , 36” , 48” , 60” , and 72”. If you need a custom length we would be more than happy to work with you on that.
