Aardwolf Battery Joint Setter - BOSS

This device works well on stone and glass with non-porous surfaces. It can be quickly closed or opened by simply moving the roller nut with the palm of your hand. The two vacuum bases are aligned with precision steel guide axles. These axles are anchored on each side with a central axle and two sub-axles. When the roller rotates, one vacuum base will move along two sub-axles and pull two pieces of slabs together. One balance bar with four leveling knobs allows surfaces to be leveled precisely. The battery-operated vacuum pump maintains an equal vacuum in both pads during the working process.
