You show two guys operating the system. It also looks like you're showing one guy doing both sides, but that was kinda unclear. Can this definitely be used by a single operator?
Hi, thank you for your question. In fact, we do not see the mending plate in this video. They are not mandatory, but they are recommended. A mending plate is a flat metal connector used to reinforce the wood joints. There are a few holes to install screws or nails to joint the wood 2 by 4.
