If you need an 8ft ramp that fits in a small space, here are your two best bets:
Multi-fold Ramps: These fold in quarters (lengthwise and widthwise). An 8ft ramp becomes a compact 4ft x 1.5ft "suitcase" that fits in most car trunks.
Telescoping Ramps: These are two separate narrow tracks that slide down to 4 or 5 feet. They are the easiest to tuck into tight corners or behind a car seat.
Quick Tip: If your step is only 1 to 3 inches high, you don't need an 8ft ramp—a small Rubber Threshold Mat (about 2ft long) is much shorter and cheaper.
