The 2000-4 shares the same innovative construction as the model 2000 but tailored for larger surfaces. The strong 15/16″ stroke of the 2000-4 is aggressive enough to level hard woods while offering the operator enough control to sand the most delicate veneers. The linear straight-line sanding action virtually eliminates cross-grain sanding “Pig Tails”. The large 4 .” x 16″ flat rubber pad insures a smooth flat finish with any abrasive. Pad Size: 4 ½” x 16″ PSA Pad with accompanying clips.
