Laguna Tools 13" Flatter Strip Set, 24 CT.

Product Details
Available here is a wide selection of abrasive strips to fit the flatter head on your SuperMax 13'' Combo Brush/Drum Sander (sold separately). If you're looking for direct replacements for the strips that came pre-installed on your Combo Sander, choose the 180-grit set. A full range of other grits is also available for everything from coarse sanding to fine finishing. Each set includes 24 abrasive units that slide into the flatter head. Each unit contains a flexible brush with a row of abrasive strips on one side of the brush. In use, the flatter strips emulate a hand sanded finish on profiled workpieces like crown moldings and raised panel doors. They are also used on veneered panels to reduce the risk of sand-through.
 
Grits available 80, 100, 120, 150, 180, 220, 280 and 320
