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 products in windows and for other fixings on glass and suitable surfaces. As Adams exclusive UK distributor, we have the largest range of strong Suction Cups or suckers for many uses in various types from hooks to mushroom head and sizes from mini to heavy duty. Our exceptionally high quality Suction Cups are professional looking that will not turn yellow or become brittle. Order online at Suction Cups Direct.
