<b> INTRODUCTION </b> <br> Mini-,magnetic hooks, compact and lightweight, inlaid with a magnet, which can be attracted by iron, steel, nickel and other ferromagnetic material.<br><br><b>YOU MUST KNOW!</b><br><b>-Whether magnetic hooks can hold 0lb,few pound,many pounds,your steel plate is decisive!</b><br>1)A thicker Steel<br>Thin steel means saturation of flux in the magnetic circuit. Excess magnetic flux is wasted in the air and can't be utilized.<br>2)Thin painting covered<br>Thick painting will give rise to a great leakage of flux,only a small portion of flux from magnetic hooks can be utilized to provide attractive force.The thicker the painting, the worse the magnetic force!<br>3)Magnetic hooks can’t attract non-ferromagnetic plate like:aluminum,cu,wood,plastic.<br><br><b>-How to achieve the advertising attractive force 30lbs?</b><br>1) Thicke A3 steel plate.<br> 2)The steel attracted by magnetic hook should be placed horizontally, no tilt.<br>3) No painting or rust covered on the steel.<br> 4) Straight upside down hanging of magnetic hooks.<br><br><b>-Straight upside down or sideways hanging?</b><br>Straight upside down hanging of magnetic hooks is recommended, though hanging method of sideways is used in the most common place.<br>Capacity of sideways hanging of magnetic hook is determined by the friction of the attracted item, it is much smaller than Straight upside down hanging of magnetic hooks. See picture#3 and picture#4.<br><br><b>Warning! </b><br><b>Please be reasonable when sticking the magnetic hooks to a thin steel with thick and smooth painting at sideways, like Refrigerator,Filing cabinet....etc,because most flux is wasted in air!</b><br><br><b>Package includes:</b><br>6pcs of 30LB large opening magnetic hooks.<br><br><b>Service:</b><br>If you have any questions about the magnetic hooks, our customer service staff will reply to you within 24 hours.
