When permanent ramps are not available, the telescoping wheelchair track ramps are an ideal solution. They can be set up to accommodate most four-wheel wheelchairs and scooters, regardless of the distance between wheels, and are ideal for short rises such as porches, stairs, and curbs. Able to extend or contract, these tracks easily deploy and lock with the simple push of a button. Available in three telescoping ranges, the shortest telescopes 36 in. to 60 in., the middle option telescopes from 48 in. to 84 in., and the largest size telescopes from 66 in. to 120 in.
