5 Stars THR5 solved our sunken living room problem

Charles from AZ wrote (January 15, 2015):

We have a 5 inch step down into our sunken living room. Our elderly friends are always struggling to step down into it and several have fallen. This ramp resolved our issue and was best fix for the price. The ramp arrived in a 5" x 5" x 26" box and was both simple and quick to put together. I like the extruded aluminum design which is light weight but sturdy. Friend can now walk or ride their electric wheelchairs easily into our living room. It could also be used at my home entry to allow smooth wheel chair or walker access. If you have a step up or a step down problem, the right THRx series can solve it.

5 Stars Easy to Install

Charlene from OH wrote (January 14, 2015):

Bought one of these from access in and out my front door with my electric wheelchair. It was installed easily in a short period of time and holds the weight of my wheelchair and I easily. Great product and well worth the cost.

5 Stars threshold ramp

Dudley from CO wrote (January 12, 2015):

seems to be sturdy and leaves me room to turn my spitfire scooter without going off the porch. I would recommend Discount ramps to everyone looking for a ramp they are not only reasonably priced but are top quality products and easy to assemble

5 Stars Perfect Product for our Needs

Bill from VT wrote (January 10, 2015):

I purchased two different size ramps and they fit perfectly because the description and dimensions on the web site was extremely accurate and completely detailed. Very simple and so easily to install. I love the quality and traction of the ramps. I highly recommend this company and their products from someone who was very reluctant to purchase off a website unable to see the product in advance.

5 Stars And I bought TWO MORE OF THESE!

Mary from MA wrote (December 31, 2014):

Not only did the 4-inch ramp work out well for my motorized wheelchair, I opted to buy two of the 3-inch ones for my garage. Now I'm completely accessible indoors and out. I'm so grateful to Discount Ramps for offering such a fine, easily assembled, safe product. Thank you!

5 Stars Fantastic Solution!!!

Mary from MA wrote (December 31, 2014):

This 4-inch ramp weight-rated at 600 pounds was just what I needed for my motorized wheelchair. It handles the weight of the chair and me with many pounds to spare! Set-up and installation was a breeze, and many have commented how safe it is and how beautiful it looks. Bravo to Discount Ramps for offering this product!! I may purchase another!

5 Stars Nice product

ICRB from OH wrote (December 30, 2014):

I bought this ramp for my father. I have yet to install it, but product seems well made. It is very heavy material that would appear to hold up to the weight of a loaded wheelchair.

5 Stars Exactly what I needed

BigD from TX wrote (December 04, 2014):

I required a ramp to offset a 1 inch height difference between the pad of my garage to my driveway so that I could roll my mobile bases of various tooling & work benches in & out of the garage. I purchased two aluminum modular ramps. This product fulfilled the need. Very pleased as to the quality & pricing of the product

5 Stars 1.5" and 3" threshold ramps.

Ray from CA wrote (November 28, 2014):

These ramps work as advertised. I've added pads to the bottom of the aluminum to as to not mar the floor. Easy to get a wheelchair in and out over a threshold that has a different height on each side. Yes would recommend to others.

5 Stars Perfect Fit

Jean Peters from SC wrote (November 21, 2014):

We needed a ramp for our grand daughter who visits us a few times a year. This was the perfect solution. Easy to assemble, and adjust easily to the slight difference in height between our front door and back patio door. Light weight, so it's easy to move and store between visits.
