Carlisle United have signed Barnet full-back Ryan Galvin for an undisclosed fee on a two-and-a-half-year deal.
The 24-year-old joined the Bees from Halifax last summer and made 13 appearances for the League Two side.
He signed a two-month loan deal with Rochdale in November but was recalled on Tuesday to allow him to make the permanent switch to the Cumbrians.
Galvin could make his debut for Carlisle, who are two points clear at the top of the National League but have played twice more than second-placed Boreham Wood, against Solihull Moors on Saturday, 17 January.
