Few covers are made for the Ridgeline's bed, and the Lo Pro 530601 is a soft roll-up cut for the 5'4" bed on the 2017-2026 truck.
Low is the point of the Lo Pro. The tracks go inside the bed rather than over the rails, so the cover rides only about 3/4 inch above them.
One anodized trigger latch opens the cover. Roll it toward the cab and buckle it down with the integrated straps for nearly full bed access, or use the quick-release system to take the whole cover off in seconds without tools.
The Lo Pro is a clamp-on, no-drill install that most people finish in under an hour with common hand tools.
Clean it with mild automotive soap and water only. Check the clamps after a week, and keep the cover secured while driving.
