Assemble your wine rack vertically by placing 4 pegs into the holes and place the next rack on top making sure the underside holes are aligned. Make sure the end connectors are all the same way. To add sideways simply slide the racks together. We recommend attaching the racks to an adjoining wall if your Vinrac system is over 1 metre high or wide. Finish by placing caps into any exposed holes. Store wine in a cool dark place.
