Abstract: A magnetic connector assembly for attaching spill boom to an otherwise featureless coated steel surface comprises a flexible plate having a front side and a back side, at least one magnet mounted to the plate to assert a magnetic field over the back side of the plate, and a connector for the boom mounted to the front side of the plate. The at least one magnet is sized to retain the magnetic connector assembly in a fixed position on a vertically positioned ferromagnetic wall with a force requiring at least 5 pounds to break.
