This crate shelf at 6-feet plastic is easy to set up. Unfortunately, the supplied tool is not available in sufficient quantity for the building of shelving available. Without an additional ring or open-ended wrench size 10 or a pair of pliers, the installation designed somewhat difficult. Prevent the enclosed self-locking hexagon nuts, which solve this without saying. Regal makes a stable impression, has a firm footing and also not so easy to tilt.
