Our 5 frame bottom boards are made with pine rails, and the main panel is made from Advantech. Advantech is a very durable and weather resistant product that will provide years of trouble-free service. Comes fully assembled.
Note: our 5 frame boxes are 9-5/8″ wide, and this bottom board is made to fit that box. Some manufacturers use 9-1/4″ boxes, so please be aware that our nuc inner covers and bottom boards will be a little bit wide if you have the narrower style box.
