Sampo Ball Bearing Swivels offer anglers maximum protection against twisted and tangled lines - an absolute must for trolling, big game fishing and spinnerbaits! Anywhere you need to eliminate line twist, Sampo ball bearing swivels let lures perform at their best. Features include highly polished stainless steel ball bearings which roll with ease and won't bind or jam, an exclusive funnel design to cut spindle-to-wall friction, and unique tapered holes mean rings and snaps swing freely and pull from the center for perfect alignment.
