These incredibly powerful magnets combine the strength of Neodymium with the corrosion resistance of stainless steel making them ideal for outdoor applications or in environments where they will come into direct contact with water. They also produce a large depth of magnetic field, maintaining a strong magnetic pull even when there is up to a 37/47'' air gap between the magnet and the material it is attracting. Each magnet is counter-bored on the north face and can be fixed in place using an M4 bolt with a maximum 23/73'' diameter head. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully.

This magnet saved me £3,000!

The objective was to remove a piece of reinforcing rod that had been dropped into a sewer during construction and revealed during final cleaning and CCTV examination of the drain.
The best solution hitherto dreamed up was to cut through 300mm of reinforced concrete floor in a confined space, break into the drain and remove the rod.The drain would then have had to be repaired and the concrete floor replaced.The whole task was estimated at about £3,000! But no fixed estimate could be obtained because of the degree of difficulty. I had to find another way.

Your website proved very useful and after discussion with one of your staff, one of your products was selected in the hope that I would be able to find a way of manipulating it into contact with the steel rod and then that the thing would hang on until we were able to pull it up to an access panel in the down pipe. The magnet was hung on a piece of string and manipulated into position with the help of an endoscope. The magnet attached its self and we were able to remove the rod at the first attempt.
The whole operation took 20 minutes with your magnet.
I don't think you will get much further business in this direction but there may occur other similar operations where this will provide a solution. My client has clearly saved thousands of pounds and endless aggravation that would have been caused working in an active commercial environment.

Many, many thanks
