Booster Automatic Boxes

The Tapepro Booster Auto Boxes have a spring loaded pressure plate which helps force the joint compound out making them easier to use. The spring power is controlled by a ratchet mechanism which is released when the box is placed on the wall, and re-engages when you sweep the box off the wall. This reduces the effort required and makes high or out of position joints much easier to fill. Code: AB-200, 250, 300
