For a professional look and reliability, use this suction cup with a long neck and gripper nubs or neck barbs for extra grip.
The distance from the base of the suction cup neck to the nubs is approx. 3mm and is ideal for posters up to that thickness where a quick fixing is preferred to a clear screw or brass nut. This suction cup can be pushed through a drilled hole of the correct dimension and the 4 x 1mm nubs will ease back out and grip the back of the poster or other product.(see technical drawing image for dimensions).
Each 47mm Adams suction cup has a weight loading of 3 pounds (1.36kgs).
