This is a brand new custom RuffRamp designed by an engineer to help our 100 lb senior labrador retriever up multiple flights of stairs. The ramp worked perfectly. We no longer need it and it can be dissassembled into 7 ramps (6 x 54.5 inches + 1 x 33 inches) and 2 landings (1 x 90 degree + 1 x 180 degrees). Each ramp and the overall structure is very high quality. We paid over $3400 for it and will sell entire ramp for $2000 or each ramp and landing section for $250.
