Brentford have completed the signing of defender Scott Barron from Millwall for an undisclosed fee.
The 26-year-old left-back, who made 132 appearances during five seasons with the Lions, has signed a two-year deal with the Bees.
Manager Uwe Rosler told the club website: "Scott has the qualities we are looking for.
"He is the right age for us and is another player who knows what it takes to be successful at this level."
Barron, who began his career with Ipswich Town, played 28 games for the south London side in all competitions last season.
