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
