Aardwolf BOSS Battery Powered Joint Setter — Cordless Seam Pulling Tool

The Aardwolf BOSS is a cordless joint setter that closes seams between stone or glass slabs. Twin vacuum bases hold each piece while a roller mechanism pulls them together. Built for installers working on counters where outlets are scarce.

Features

  • Cordless 12V rechargeable battery operation — no air hose, no cord
  • Dual vacuum bases lock onto each slab with a quick-release valve
  • Battery vacuum pump maintains equal suction on both pads
  • Precision steel guide axles keep the pull stroke true and aligned
  • Four leveling knobs on the balance bar align slab surfaces flush
  • Light, compact body for one-person countertop seam work
  • Ideal for mobile installs with no external power available
  1. Charge the 12V battery fully and confirm both vacuum pads pull rated suction.
  2. Wipe both slab surfaces clean of dust, water, and stone slurry.
  3. Position the BOSS bridging the seam and engage both vacuum pads.
  4. Adjust the four leveling knobs until the two slab faces sit flush.
  5. Turn the roller to draw the slabs together until the joint closes.
  6. Apply seam adhesive, hold position until cure, then release the pads.
