The Clear Plastic Corner Guards 312 are a good way to protect corners from hand carts and dollies. 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" by 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.
