MBW 36 inch trowels have a new look ... but it's much more than a cosmetic improvement. The new models offer a flatter profile stationary guard ring which not only satisfies new ISO safety standards but enables finishers to clean and change blades easily. The guard ring also comes with a standard edger section which allows finishing very close to walls and columns. Very importantly, the new models feature a patent pending "Low Vibe" handle offering the industry's lowest hand arm vibration levels. And the height adjustable operator's handle is now tool free.
