Aardwolf Battery-Powered Stone Miter Clamp ABMC – Vacuum-Assisted 90° Seam Jig

The Aardwolf Stone Miter Clamp ABMC is the battery-powered, vacuum-assisted version of Aardwolf's miter clamping jig. It holds two mitered pieces of granite, marble, quartz, ceramic, or porcelain at a precise 90° while the adhesive sets — finished side up, so the fabricator can see the seam and work the glue for a clean joint. Grip range runs 2 in. to 9 7/8 in. (50–250 mm), and the unit weighs 26.4 lb (12 kg).

Not the right tool for: lifting or moving stone — this is a gluing jig, not a lifting clamp, and carries no working load limit.

A: The battery-powered vacuum holds the clamp bodies to the slab faces, so the jig anchors itself while you square and tighten the joint.

A: Yes — the ASMC250 is the same clamping jig without the powered vacuum assist.

Q: What materials does it work on?
A: Aardwolf lists granite, marble, engineered stone, ceramic, and porcelain.
