Our Magnetic Clip features a super strong magnet that keeps a firm hold on our Speed Openers. The magnet is buffered by a smooth plastic pad to help protect your speed openers finish. Clips securely to a belt for quick and easy access. Note: "DOG BONE" style openers are NOT magnetic. If you are using an opener from a different source, please be sure it is magnetic first. Not all metal products react with magnets.
