A: Hi Ray,
Thank you for contacting IndeMedical.com!
The Elev8 Threshold Wheelchair Ramps largest size is 48" Long x 32" or 36" Wide. For a 5" rise you need at least 36" in length, however this ramp does not secure in place, it aligns directly against the door or threshold.
We recommend reviewing the PVI Solid Wheelchair Ramp linked below. Choose the 3' or 5' length depending on the incline you're comfortable with. The ADA recommends 1:12 ratio, 1" in rise = 12" in length. This ramp has a "lip" at the top that can be secured in place.
PVI ramps ship within 2 days of order via FedEx from NE.
