my pool locking knob had broken from the sun I would imagine. I purchased this new one for my Hayward filter and it was a perfect fit and very easy to install to the existing system.

Good quality brass amp; plastic OEM part. Note that the threads are way up in the center hole, you need a flashlight to see them. Originally I thought the part was defective but it is not. Youtube has good videos to help install it. I bought an open box one so was a good price.

The part is good, I just didn't realize that I didn't need it till I looked closer. My filter top was popping up and causing it to leak. I searched the web determined the threads were bad on this locking knob. But after installed, it was not better. I then realized that problem was the threads on the rod this piece screws on to. They had become filled with salt/corrosion so that I couldn't tell the threads actually extended well down the rod, not just the last half inch or so. Wire brushed em out then the knob could seat all the way down. leak fixed.
