Drywall is a surface that can handle a very large amount of weight, IF properly hung. The key to hanging heavy objects on drywall is using the right hardware on both the wall and the frame. OOK Heavy Hold Products are designed for professional, heavyweight challenges. The principle is to use the leverage of a small surface area in the back of the drywall. The more surface area, the more holding power. Additionally, the OOK Heavy Hold hangers employs a spiked shaft, that “nails” into the rear of the wall as well as the front. This provides for up to 300 lbs of holding power.
