This variable wall spacer is used to space planks from the wall to form the expansion gap necessary with plank floor installations. It provides variable spacing when the wall adjacent to the planks is not straight. It operates with a large threaded pushrod that's attached to an ergonomic twist knob. Additionally, the twist knob has a steel hex insert for use with a hex wrench for extra force. With the extra leverage, the tool can be used for pressing together the butt joints of end planks. The pressure pad has a rubber insert to prevent scratching of walls. Hex wrench not included.
