Q. Where do I attach the Click-on Adapter?
A. You screw the threaded end onto the Hoselink Accessory Connector (that has a male thread).  If you are trying to attach it to a hose already set up with Hoselink, unscrew your sprayer or Swivel Connector, this should leave you with the threaded end of the Accessory Connector - now screw the Click-on Adapter here.

Q. What's the difference between the Click-on Adapter and the Click-on Adapter Set?
A. The Click-on Converter Set includes an Accessory Connector with the Click-on Adapter, making it easier to connect and disconnect from your hose.  You don't have to screw and unscrew it from your watering accessory, making it more convenient.
