Standard 11-Segment Trapezoid Prep Tool

This Inland 11-segment trapezoid mounts to a wide range of bolt-on grinders and is great for mastic removal — the 11-segment configuration puts more diamond contact on the floor to power through mastic, glue, and adhesive residue. A standard-attachment trapezoid built to fit SASE®, Diamatic, CPS, Klindex, and other bolt-on machines.

Call for pricing, availability, and the right grit and bond for your work — you’ll talk to a real surface-prep expert, not a call center.

Best for Mastic Removal

The 11-segment design shines when you’re stripping mastic, glue, and adhesive residue. More segments mean more diamond in contact with the floor, so you power through gummy, stubborn mastic that can bog down tools with fewer segments. When the job is removal, the 11-segment gets it done.

Choosing Grit & Bond

Match the tool to your job:

• Grit — 16 (most aggressive) through 120 (finer); coarser for heavy mastic and material removal, finer for a smoother follow-up
• Bond — Soft, Medium, or Hard; softer bonds for harder concrete, harder bonds for softer concrete
