Construct a right triangular prism-shaped wedge from a rigid material (steel, wood, aluminum, or equivalent) as shown in figure 1.

Place the wedge midway between two vertical components and midway between the top and bottom horizontal rails. Attach a dial push-pull gauge (Chatillon model DPP-50, or equivalent spring scale) to the eyebolt and exert a 9-kilogram (20-pound) direct pull on the wedge. The test may be performed by suspending a 9-kilogram (20-pound) weight from the eyebolt with the crib component placed in a horizontal position.
