Slimline Limpet Magnet for Semi Permanent Attachments 50mm dia x 3.5mm thick 6mm hole 30kg Pull

IDEAL FOR SEMI-PERMANENT ATTACHMENTS. Because these magnets are so thin but so strong they are ideal for semi-permanent attachments such as pictures, noticeboards or other hangings on steel walls.

Each limpet magnet can support a steel weight of up to 30kg vertically from the magnetic face when in flush contact with a mild steel surface. DUAL FACING POLES. The north pole is outward facing on three of the magnets while the south pole is outward facing on the other three creating a north-south-north-south striped magnetic field.
