Excess 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 base can be utilized to provide force.The thicker the painting, the worse the force! br 3)hooks can’t attract non-ferro-plate like:aluminum,cu,wood,plastic. br br -How to achieve the advertising force? /b br 1) 0.08 inches or thicker A3 steel plate. br 2)The steel attracted by hook should be placed horizontally, no tilt. br 3) No painting or rust covered on the steel. br 4) Straight upside down hanging of hooks. br br -Straight upside down or sideways hanging? /b br Straight upside down hanging of hooks is recommended, though hanging method of sideways is used in the most common place. br Capacity of sideways hanging of hook is determined by the friction of the attracted item, it is much smaller than Straight upside down hanging of hooks. br br Warning! /b br Please be reasonable when sticking the 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 Package includes: /b br 10pcs steel hooks. br br Service: /b br If you have any questions about the hooks, our customer service staff will reply to you within 24 hours.
