ARO Plank 8

ARO Plank 8 is anything but ordinary with chamfered acoustic planks set at varying depths to cast compelling shadows. With five modules that install in three standard patterns and hundreds of leather colors, the planks install quickly and easily with Spinneybeck’s Interlock Mounting System.

  • Installation Planks install with Interlock Mounting System provided (wall fasteners not included)
  • Maintenance For finished leathers, wipe with a cool, damp cloth. For tougher soiling, use a pH-balanced soap such as Dawn with a 1:10 ratio of soap to water and rinse. Repeat, if needed. Occasional use of Spinneybeck Finished Leather Cleaner, Conditioner & Protector is recommended. For naked (aniline) leathers, wipe entire surface with a soft cloth and cool water to even out any abrasions or stains. Do not spot rub, for it will darken only that area. Occasional use of Spinneybeck Aniline Leather Cleaner, Conditioner & Protector is recommended. Other leather cleaners such as saddle soap or household cleaners that may contain harsh chemicals, alcohol or ink removers should never be used.
  • Variation Color variation of naked leathers may be more pronounced beyond the normal commercial range. A Cutting for Approval (CFA) is required for all orders.
