Small enough for your fin box, strong enough to keep your board safe The SUP & Surfboard Fin Box Lock is a simple yet effective way to lock up your board while you are at the beach or transporting your boards on your car racks. Simply slide the 2 board lock plates into your board's fin box, alight the holes, and run a cable/lock through to secure your board to a nearby anchor point. Lock your board to a bench, dock, or car rack to make sure it doesn't walk away while unattended! 

Compact for travel The Lock System is lightweight and compact making it easy to toss in your surf bag or SUP fanny pack while you are out on the water or traveling. 

Complete Lock System Add the optional MasterLock Python cable to complete the lock system. The cable is 3/8" thick, 4 ft. long, and covered in a protective coating for use outdoors. The locking plate is large enough to feed the cable through or attach your own padlock.
