Side Inserts --When using the installation points on the sides of the cabinet, you must use the included bevel washers. These washers provide a uniform flat surface for the shoulder of the bolt and also compensate for the draft (angle) of the sidewalls of the cabinet. In this application, the thread length must be longer to reach through the washer, while not “bottoming out”. The shaft should be 25.4 mm (1 inch). See Figure 3:
For side inserts, use 6 mm x 1mm pitch x 25.4 mm thread length
steel forged shoulder eyebolt.
CAUTION
Installation must only be done by qualified persons using safe rigging practices. Load eyebolts in accordance with the eyebolt manufacturer’s loading guidelines.
