This is our second generation Cat Fort made from our Cat Mod line. A few things that set it apart from our original version: -Hidden brackets system creates the illusion of ‘floating furniture -Removable fabric for easy cleanup -Freedom to either use our layout or create your own design The Cat Mod Fort is a really nice medium-sized complex for spaces without a lot of horizontal space. For the layout shown it uses three studs spaced out at 16. Since this is part of our Cat Mod collection, you can set it up using the step by step instructions to create the layout weve come up with or since its a modular system, you can also build it many other layouts to perfectly fit your space. This piece is mounted along three 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.) The Fort comes in your choice of Onyx, English Chestnut, or Unfinished wood. All sets will come with the canvas color of your choice and Nickel mounting hardware. Includes: 170 Canvas fabric 18 Sisal-lined escape hatch 9 Mounting planks 2 Ladder pieces Would you like to add a Feeding Station or fun Planter onto your wall-mounted setup? Check out our Cat Mod Add-ons. Standard Dimensions: Total Width: 38 Total Height: 60 Depth: 11 (This measurement is for the layout in the primary image for the package. Because the Fort 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. 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!
