Practical ferrite magnet holders with vertical (upward facing) adapter for attaching sign frames to ferromagnetic surfaces. The magnetic holders allow easy and flexible positioning of poster frames in no time. Perfect for labelling shelves with poster frames in retail or warehouse settings without having to drill holes or use screws.
When used outdoors, individual components of the magnetic holders can accumulate flash rust, but this does not impair their function.
Please note: The full adhesive force is achieved when the ferromagnetic counterpart is smooth and of sufficient thickness and when the pot magnet makes direct and full flush contact. Pot magnets already lose much of their adhesive force at a distance of only half a millimetre to the ferromagnetic surface. This characteristic is more pronounced in pot magnets than in other ferrite and neodymium magnets. You can find additional fascinating information on our FAQ page about pot magnet features.
