No affiliation, very happy customer, CGS makes some niche custom add-on racks and stuff that really make most kamados more flexible. They have a Christmas sale, and it is rare that they have sales.
I use their Woo ring in my Kamado Joe Jr, makes it easier to remove the deflector and grate as a unit, esp when hot.
I use their expander rack in my Big Joe, and it is more flexible and more convenient than the Kamado Joe extender rack (KJ only fits one specific position, and has 3 vertical feet, while CGS is a fully round support ring and can even be used without a grate in place, it sits right on the grate support nubs). CGS expander rack also has an optional deflector holder and 2pc top grate so you can flip it up for easy access to the center of the main grate, as well as so you can use it as an indirect warming rack above one extra deflector.
I've recommended them earlier in this thread, some of their accessories allow you to drop a grate down close to the coals for searing. They also have a variety of grate and drip pan sizes if you're having difficulty finding one for your exact smoker size.
For Green Egg users, the CGS grate systems are a huge improvement in cooking flexibility. Not so much for KJ users.
No affiliation whatsoever. I sound like a spambot. I'm a happy longtime customer.
