Review (4/5): Good value - Qualty trays
Good product. I create plywood bases for my power tools so that I can move them around from table to table and clamp them down. I use these boot tray's underneath the tool (like a grinder) to protect the wood from anything the tool produces and to give one common look for the tools. It also serves to hold that tool's accessories and power cord. I can also flip one up against the wall behind the tool to shield the wall from the overspray.
I also use them under the sink to protect the cabinets. Sorry if this sounds like a promotion, I chose these because of their rectangular no frills design.
