It can be attached simply by snapping it into the FCS2 compatible plugs, and there is no need for screws or keys, making it very easy to attach and detach fins! Also, you can attach conventional FCS fins by using the infill kit. It is designed with consideration, such as a mechanism that allows sand to drain out and the use of titanium, a rust-resistant material!
