## Description

Hold blueprints, calendars, important memos, visual aids, work plans, and more with the Master Magnetics ceramic round base magnets with knobs. In vertical testing, each magnet holds up to 16 lbs when in contact with a 0.25" thick, smooth, flat ferrous plate. The force is 50% less on a vertical surface holding against sliding force and less on steel that is painted, rusted, dirty, or damaged. The 1" diameter knob provides a 0.425" clearance from the magnet base, offering a comfortable grip for easy positioning and removal. Enclosed in a durable nickel-plated steel cup, these heavy-duty magnets are ideal for use in homes, workshops, offices, and industrial settings.
