Knob, Height Adjustment (Set of 4) for Medline Ultralight Freedom Rollator

They do what they are supposed to do

Fit, worked

I purchased the tri-winged handle knobs for walkers. I had lost one and needed to replace it quickly. I used a screw until my order came in.

The walker is missing the button on left side, I am left handed. After surgery, the physical therapist brought this to my attention, that it is unsafe due to that face no instructions included so I had no knowledge of this.
The adjust handle needs more holes to lower for short folks.
It came without any instructions what so ever. It would be a good purchase after these issues are addressed.

We now have extras in case we lose another knob.
Couldn't be happier.
