Each 47mm Adams suction cup has a weight loading of 3 pounds (1.36kgs).
These strong gripper suction cups have a long neck with protruding nubs around their circumference. They are great for posters which are 3mm in thickness and where a quick fixing is preferred to using a top pilot hole suction cup with a clear screw or brass nut fitting.
The suction cup can be pushed into a drilled hole of a poster or sign and the nubs will ease back out to grip the back of the poster (see technical drawing image for dimensions).
Suction cups are ideal for hanging items on glass. Adams superior suction cups will not deteriorate or lose adhesion over time.
