This clamp/jack is a blast! From the manufacturer: The jack can lift cabinets up to 15-3/4" tall with a 100 pound capacity. Maximum clamp width is 13-3/4". I use these clamps/jacks to install cabinets. If you use it as a jack you can lift the cabinet onto the level and then attach the paneling. Done. I've also used jacks to install sheet metal panels It is very difficult to install sheet metal siding on the wall by yourself, lift and nail it in place.After placing the sheet metal siding on the wall, use jack stands to lift the sheet metal siding and nail it.Done. These terminals/sockets are also good for clamping I have seen them for years but never used them until recently Excellent merchandise.
