I bought four pairs of these brackets to make some inexpensive saw horses to hold material while painting. I wanted something cheap and easy to set up. The cheap thing was a given but I did not expect it to be so wobbly. Also the easy to set up was untrue. Granted it is easy to cut some lumber and screw it together but it took way too much time. Also, after I used the horses a few times, the metal began to bow out and made them even more wobbly.If you are looking for a one time use cheap item, this is it. If you intend to use it as a temporary scaffolding, you better get some good health insurance, since you will going to need it.Frans.
