CX900G Pool Filter Locking Knob and CX900DA Knob Kit Compatible with Hayward Star-Clear Plus Cartridge Filter Models C751 C900 C1200, Replacement for CX900D/CX900H/CX900W

This came with all the necessary parts to replace the old knob which had become stripped over the last nine years.

Once I received the parts, I cleaned off the threads of the stainless steel Hayward rod with a wire brush, lubricated the threads and then installed the knob and parts per the Hayward parts diagram. My Hayward filter now is easy to open and close like new.

The perfect replacement parts. Quality appears to be as good as OEM or close enough considering the price difference.

Parts fit perfectly, very easy repair, I watched this video which explained every step. Basically it saved me lots of money. I also added a new pressure gauge. Images show a broken top handle which was also stripped and would no longer tighten along with an old broken pressure gauge. Every part fit perfectly and everything is working better than it has in years. 5 stars!!!! https://www.youtube.com/watch?v=iFyzRdwrdF8

So happy it arrived on time. Followed instructions on YouTube. Replaced knob for pool filter housing in no time and works great!
