Question: how do you install on plywood backboard
Answer: Thank you for your inquiry Linier racks can be mounted to the wall using a Kendall Howard 0300-1-001-00 wall mounting kit. I have not personally heard of a customer mounting a Linier rack to plywood, but Drywall and stucco (softer materials) have been both tested to work. Please note, the quality and thickness of your plywood will determine the weight capacity of your rack, and if mounting will work. The process for mounting: 4 toggle anchors, 4 washers, and 4 bolts - drill a 1/2 inch hole in the wall, insert the toggle end of the anchor into the hole, slide the fitting tight against the wall and snap off the 2 zip lines. Simply line up the cabinet or rack you are mounting and screw in the bolt. To see illustrations of this process, please click here.
