STI Edge Plate – Prep Master 2807 & 2818

The STI Edge Plate lets your STI-2807 grinder get right up to walls and edges — so you can grind and prep the perimeter of a room without switching to a separate hand grinder. It’s the part that helps you finish the whole floor, edge to edge, with one machine.

• Edge grinding — reach close to walls and edges
• Finish the perimeter without a separate edging machine
• Designed for the STI-2807 grinder

Why You Need It

A standard grinding head can’t reach all the way to a wall — which leaves an unground border you’d otherwise have to hit with a hand grinder. The edge plate lets your 2807 work right up to the edge, so you cover more of the floor with one machine and skip the extra step.
