Q: Is it easy to move the Retractable Hose Reel from one faucet to another? 

It sure is!  You will simply turn off the water, disconnect the leader hose from the faucet and pick it up using the two built-in handles. Keep in mind, water is heavy! Be sure to drain as much water from the hose before lifting it out of the bracket.  

Q: What is the size of the hole on the Second Bracket?  

It is a 1" wide hole.
