The PawStep 50524 61" Portable Folding Pet Ramp is designed to provide pets with assisted access to vehicles and elevated surfaces. The ramp is constructed from durable molded polypropylene (PP) plastic, making it lightweight, rust-resistant, and easy to clean. The walking surface features a molded ribbed texture intended to help improve footing. However, as the ramp is made from hard plastic, traction may vary depending on factors such as ramp angle, vehicle height, pet size, and surface conditions. For pets that require additional grip, customers can select a compatible anti-slip carpet accessory or choose a version of the ramp with the carpet pre-installed. The ramp supports pets up to 165 lbs and folds for convenient storage and portability. It is suitable for use with cars, SUVs, beds, couches, and similar applications. For best results, the ramp should be used at a moderate incline and on stable surfaces.
