This floating ramp allows dogs to easily get in and out of a boat, lake, or pool on their own. As the dog steps onto the ramp, the bottom slowly submerges, creating a slightly sloped walking surface that simulates the gentle grade of a shoreline. Eliminating the need to lift your pet into a boat or out of a pool, the ramp simply hooks to a boat or dock cleat for temporary use, or installs permanently onto a concrete, wood, or fiberglass dock (instructions provided). It accommodates dogs weighing 10 to 90 lbs.; simply unsnap the under-mounted Styrofoam floatation device and move it towards the bottom of the ramp for heavier canines or to the top for lighter dogs. The ramp is made using 100% marine-grade components, stainless steel hardware, and a mildew- and fade-resistant carpet that is soft on paws. Ideal for docks 6" to 28" above the water line. 84" L x 20" W x 3/4" H. (28 lbs.)
