I posted earlier but not sure if it worked as I can't find it. I'm a quadriplegic and use a wheelchair but always trying to do better. I looked at these parallel bars but they are so expensive. I want to practice standing up and doing squats unassisted but a basic walker isn't stable enough. Wondering what parts / pipes / brackets / base I would need to make something like this? And it can be shorter, maybe square instead of parallel since my focus is standing right now and being able to move it around without much difficulty would be useful. Hoping that there is some fitting that would be able to make the pipes height adjustable??? If not I would make do with a set height. I truly appreciate anyone that can tell me how and what items I would need to make this and or other suggestions. Thank you!
