This sawhorse is CNC cut and features double laminated legs that are 1 1/4" thick. It's bolted together with nylock nuts. It folds closed when not in use. This is not only one of the strongest sawhorses that you'll find, it's also one of the most beautiful.
The top crossmember is traditional dimensional lumber and can be modified or replaced at anytime by simply drilling two holes and bolting it back to your base.
