This Delta Abrasive Systainer® stores any abrasive in a dedicated space and is clearly organized, efficiently protected against moisture, and always close to hand. The pivotal point of the systainer is the T-Loc, the central control element: Close, open, and connect with just a single turn. A particular time-saver is that the systainer T-Loc can be opened without having to disconnect it from the other systainer beforehand. The insert fits dia. 3-1/2" (90 mm) abrasives and V93 abrasives.
