Bought this ramp to accommodate a steep, 2" gap at the backdoor threshhold. The ramp allowed for an easy way for moving furniture and appliances. It also creates a mild rise to walk over the 2" gap at the door. The rubber does not invite "pests" and will not create a dusty place for creeping crud. It's so quiet! So much easier to see the floor, too. It's just the thing! Thank you, Vevor!
