Our cats tear around the house on these Raceways and relax on them as hammocks when they finally tire out. This is the largest of our Raceways, at a little over 6.5-ft long when mounted. There is enough room for multiple cats to play around, or one very spoiled cat. Each Large Raceway is built to be mounted among six consecutive 16 studs. (If your studs are spaced differently, let us know before ordering and, if necessary, well build you a custom piece accordingly for an additional fee.) We use solid wood for the mounting posts and thick heavyweight canvas for the hammocks. Brackets come attached for easy installation. All of our furniture also comes with screws. Weve tested the individual wooden planks to hold 85 lbs, and the fabric spans to each hold 62 lbs. We have new easy-to-wash, waterproof marine canvas! With this fabric, cat hair and other debris wipes off quickly with a wet towel If you want this option, just select a fabric that says “Waterproof” in the drop-down.
