Aloha! My profile says I didn't reply to you but I did, however I'm brand new to this so if you didn't get my reply I'm so sorry! I had an older model of this years ago that had a cap but this newer model just snaps on. It's very easy plus you can flip it over to work on either side of your faucet so it's not in your way. I really liked that feature. Thanks for looking. Kathy
Hi! I use to have the old kind with the cap but this newer one just snaps on. It's a lot easier than the old one. You can also flip it so it can be on either side of your faucet.
