Heavy Duty Magnetic Hanger - Eyelet, with Removal Hand Tool

This is a heavy duty (~70 lb./32 kg pull force) magnetic hanger or eyelet, with an included removal tool. Its purpose is to provide a temporary and removable eyelet or anchor point, by attaching the hanger to a metal surface. It is specifically designed to be used for temporarily mounting UV lights to the steel framework of a standard acoustic hanging/floating ceiling, but it has many uses (see attached photos). In the past, I used spring clips that were difficult to work with, that sometimes damaged the ceiling tiles, and almost always caused particles of the acoustic ceiling tile to fall down on the floor (or in your eyes).

This design requires purchasing the heavy duty bar magnets which are 60mm x 13.5mm x 5mm (see the attached photos). These magnets are widely available. The magnets are touted to have a pulling force of up to 70 lbs./32 kg, so they are a bit difficult to remove by pulling directly away from the surface, as one might try to do with something stuck to the ceiling. However, they can removed fairly easily by pulling and rocking the magnet to the side, thus breaking most of the magnetic attraction. The removal tool is designed to make this process easy, by simply pulling to the side and lifting away the magnet (especially if one is required to remove the magnet from a tall ceiling while standing on a ladder).

The removal tool is deigned to fit the hanger with or without a carabiner attached (see attached photos). 

This hanger is designed to accept an M5 x 50mm small carabiner to make attaching it to many objects easier. However, one could simply tie a cord or string to the hanger eyelet.

The magnets typically come with, and are designed to be installed with, two .5 inch/12.7mm screws. However, I designed the hanger to accept up to .75 inch/19mm screws, for a stronger hold. I also assembled the magnets and hangers using 5-Minute epoxy. There is an intentional gap designed between the magnet sides and the inner walls of the hanger. This is to allow the epoxy to squeeze out the sides a bit and adhere to more surface area of the magnet.

The model must be printed with supports, but clean up is fairly easy.

NOTE: I also designed a lighter duty version of this this type of hanger, for hanging up lighter weight objects. There is also an installation tool for the Lite hanger version, which attaches to a standard ¾ x 5 ACME thread tip of an extension pole. This makes it easier to hang objects from the ceiling without needing a ladder:
