Easy to assemble and heavy duty. Wife uses a power wheel chair and it supports her and wheel chair without any movement. I can recomend this ramp. However, for a 3" rise it is a bit of a steep incline.
I am pleased with the ramps. They are serving the purpose intended to the doorway entrance. They are also strong and steady. My mother has easy access in and out of the doorway with her walker
I used the ramp to transfer items on dollies in and out of my garage. The ramp is stronger than expected.I rolled an engine and transmission (LS1 and T56 mounted to a stand with casters) across it. The ramp flexed but did not bend.
