Rollator Height Adjustment Knob,Deluxe Aluminum Rollator Accessories - 3 Point Knob W/Bolt, Rollator Parts -1Pair(2PCS) (Black)

The item was as described. These were bought for a Nova brand rolling walker and they fit. Took some effort to get them started because the upper part of the bolt shaft is just a bit larger than the same on the stock knobs. A little pressure and perseverance and they worked. On the plus side they are not likely to work loose.

The knobs are slightly larger than the original but the shaft is the right fit for the Rollator. Great substitute replacement product.

Used these before. They do seem to loosen with time. Check them every so often!

I bought this for my wheelchair and it works well. I’d recommend everybody to buy this if you needed it.

Arrived when it said it would No problems thus far, seems to work well but it doesn't lock tight, don't know if it suppose to or not. It keeps the arm in place, that's all I ask

These are hard to find, even in a well-stocked hardware store! Thread is the same, size is comparable, very happy with product! Will order more when another customer needs replacements!

Exact replacement for lost part. Learned to check that knobs are tight after rollator has been moved in and out of vehicles. Glad it’s sold as a pair - extra on hand for any future issues.

I disliked that they did not fit, for I thought they would be universal within the same product line.
