The Climb Track is the perfect full setup. Our cats love the Vertical Sisal Pole, but we always had to set up our walls to give them a route down once they got up to the top. For the Sky Track, we combined a 4′ Vertical Sisal Pole with some of our other pieces so that the route down is built into the complex. This set is a great option for homes with multiple cats or one spoiled cat! Having sisal pieces around our home has completely stopped our cats from scratching the furniture. This piece is mounted along four studs, spaced 16 apart. (If your studs are spaced differently, let us know before ordering and, if necessary, well send you a custom setup accordingly for an additional fee.) This complex comes with a 4-foot tall vertical sisal pole, with fabric attachment mounts on the left. The Cat Mod Climb Track comes in your choice of Unfinished, English Chestnut, or Onyx wood. All sets will come with the canvas color of your choice (second option upon choosing the item) and Nickel mounting hardware. We use solid wood for the shelving and mounting posts, and thick heavy-weight canvas for the hammocks. All of the brackets come attached for easy installation. Includes: 154 Canvas fabric 4′ Vertical sisal-lined pole 18 Sisal-lined escape hatch 6 Mounting planks 2 Ladder pieces Would you like to add a Feeding Station or fun Escape Hatch onto your wall-mounted setup? Check out our Cat Mod Add-ons. Were excited to introduce the Cat Mod, the second generation of our fabric cat complexes. When creating the Cat Mod, we made sure to maintain all the positive aspects of our original collection of cat hammocks and complexes, such as strength, appearance, and quality, while also adding some new and exciting features that elevate it from the original collection. Our new patent-pending system has a lot of great advantages, including its washable cotton canvas. This system allows you to remove the fabric from the structure without having to take down any of the mounted planks from your wall. Not only will this make cleaning a breeze, but it will allow you to continue to build the structure at your leisure. This gives you the option of switching out canvas fabric colors down the road. The mounting hardware is no longer visible when our hammocks and complexes are mounted on the wall, giving the planks an attractive “floating” look. Another great feature is that these complexes are modular; you can build any design you dream up. The Cat Mod system is like the building blocks you used as a kid in the sense that we created it to allow customers to build on or rearrange the pieces for limitless design options. We will be including schematics to build some standard configurations, but we hope to inspire you to come up with your own unique complexes! Standard Dimensions: Total Width: 50 Total Height: 85 Depth: 11 About The Cat Mod (This measurement is for the layout in the primary image for the package. Because the Climb can be used to put together so many different layouts, there are also a lot of different measurement options.) We use solid wood for the mounting planks and thick heavyweight canvas for the hammock. Brackets come attached for easy installation. All of our furniture also comes with screws for mounting.
