very good product

### ⭐⭐⭐⭐⭐ Fits old radiator
*by R***N on November 9, 2025*

Works exactly as needed/expected. I live in a house they expect was build around 1910. We have radiator heaters and, as one does, have long since lost the key. I have carefully used pliers in the past but worried we would damage them so I ordered this to try to bleed them. Came on time, I was initially discouraged because none of the arms fit, but the center was a perfect fit. We were able to safely bleed all radiators without damaging them in just a few minutes each.
