The Deluxe XL has the same construction as our Deluxe Telescoping model, but is 17" longer and 3" wider-45% larger overall The extra length of the XL model provides a flatter angle for easier climbing. The extra width gives larger dogs more room and thus more confidence when using the ramp. Sporting Dog Owners: For use with 4x4 pickups, the extra length in this model is essential. The unique construction of the XL model gives it the best combination of size, strength and light weight on the market. Even though it's "oversized" it still weighs only 18 lbs, and it supports over 300 lbs. It,s also very compact, making it easier to use and store. It extends from 47" to 87" and anywhere in between. Use it fully extended for SUVs, pickup trucks, grooming tables, etc. Shorten the ramp when space is limited or when the upper surface isn't as high-the Deluxe XL Telescoping Pet Ramp is many ramps in one. The telescoping design is the secret to making this ramp so easy to use-just slide it out to use and slide it in to stow. No clumsy folding and unfolding required. A high-traction walking surface gives pets a sure footing, especially on steep climbs. The ramp also includes a convenient carry handle, and safety release latch to prevent accidental opening. The ultra-stiff design utilizes four rubber feet to keep the ramp stable while in use.
