ARO Plank 2

ARO Plank is a wall system composed of modular planks that assemble to create standard patterns, yielding a continuous architectural finish. ARO Plank 2 has two distinct faceted modules: Wide (A) and Narrow (B). Modules have angled edges and rotate 180 degrees for additional variation in pattern. Composed of leather-wrapped PET substrate, Plank 2 is available in five standard configurations. Planks install quickly and easily with Spinneybeck’s Interlock Mounting System and are available in a wide range of leather qualities and colors.

  • Leather Colors Refer to Color Book for available colors
  • Seam Options Top Stitch or Blind Stitch—Seams are machine stitched at random intervals in matching thread color unless otherwise specified
  • Components Includes planks + Interlock Mounting System (wall screws not included)
  • Maintenance For finished leathers, wipe with a cool, damp cloth. For tougher soiling, use a pH-balanced soap and rinse. Repeat, if needed. 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. Other leather cleaners such as saddle soap or household cleaners that may contain harsh chemicals, alcohol or ink removers should never be used.
  • Lead Time Made to order and certain lead times will apply
  • Custom Custom configurations and seam options available—lengths beyond 9’-0” (2.74 m) must be quoted
