The NRS Oar Tether keeps that oar anchored to the boat if it pops off the oarlock or pin. The quick release buckle lets you easily remove your oar when needed. The NRS Oar Tethers, made of a polypro strap, gives you a fighting chance to get the oar back in before the next wave. Stainless-steel rings secure the tether to oar mounts and oars.
