This is the replacement Impeller Shaft Assembly for the Magnum 350 canister filter. The Magnet Assembly and the Impeller Housing are sold separately.Size:1 14" long x 3 34 wide.
Magnet assemblies are used for mounting, lifting, holding and transferring objects, such as pot magnet, magnetic channels, magnetic catchers, plates, wheels etc. In order to install magnet assemblies, make sure the demagnetizing field is parallel to the pole pieces. Also, be sure that at least half of the length of the holding assembly is outside the maximum demagnetizing field. To easily remove the part, mount the assemblies with their pole pieces parallel to the direction of release motion. In applications where gravity is a large part of the release mechanism, pole pieces are mounted parallel to the ground.

Pair of Ferrite magnet assemblies each containing 2 trapazodial magnets between 2 steel plates supported by steel spacers. Each magnet is 1/4" Thick X 5/8"tall X 3/4" wide (max).Two powerful, shiny neo-dymium magnets facing each other, on metal brackets. The brackets are easy to separate, but the magnets are not easily removable from the brackets. Irregularly shaped magnets are approximately 1.74" long x 1" wide x 0.06" thick. This is a typical magnet assembly, some have two small magnets that are side by side. The magnets are cemented to their mounting plates. You may be able to break the bond and get them off, but often this breaks the magnet. I leave them on their mounting plate which makes them easier to handle.
