This neodymium channel magnet has 45 lb holding power, which is 13 lb stronger than the same size N52 magnet NB022-52NM. i.e 2L x 1/2"W x 1/4" Thick!
This neodymium channel magnet is made of a super strong neodymium magnet encased inside a chrome plated steel circuit which triples the holding force to 45 lbs, which is 15 pounds stronger than an equivalently sized standard channel magnet! At the same time, the steel channel also protects the magnet from being damaged during day to day use. It’s perfect for use as a cabinet latch, to keep nuts and bolts in one place, or even tools handy. There are two #6 countersinks at each end of the magnet to allow for a flush installation to maximize holding power.
