The Clear Plastic Corner Guards 313 are a good way to protect corners from hand carts and dollies in areas of lighter traffic. If the area has a lot of traffic, like a warehouse, I would recommend the 310 or 311 which are made of metal. The are 2-1/2" by 2-1/2"" and are usually 48" long, but we can do custom sizes. They are constructed of .120" thick clear polycarbonate plastic. Screws are included for mounting.
