N52 Small Rectangle Neodymium Magnets 1/2 x 1/2 x 1/8" Rare Earth Rectangular Magnets
This powerful neodymium block magnet measures 1/2" in length, 1/2" in width, and 1/8" in thickness and is made of a grade N52 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality control systems and are plated in a nickel-copper-nickel triple layer coating for a shiny corrosion resistant finish. This magnet has innumerable uses as a holding magnet, but is also great for an assortment of both industrial and personal applications can be used in an almost unlimited amount of ways.
Please note that all neodymium rare earth magnets are fragile and require extreme caution when handling due to their brittle nature and to avoid injury due to pinching.

I got 6 of these to use for prop making but we had just build a bamboo wall to a wooden bar that we use as a door to block off a part of the yard for the chickens. Did not have a great way for securing the door so I put three of these magnets into the coup and three into the wooden vertical bar. Used a thin metal strip to cover them after placing into a carved out indent. Probably could have used stronger magnets but it works perfectly now and has been for the last three weeks. As always, the super fast shipping, magnets being marked for polarity, plastic separators between magnets, and perfect build are why I do all my magnet shopping from this site. Always will recommend.
