McManus, who was originally on the books at Crewe Alexandra, was the club’s longest-serving current player, having joined in 2011 from FC United of Manchester.
After arriving as a central defender, McManus soon made the successful switch over to the left-hand side of defence and has made the position his own.
The Manchester-born defender scored in the Buildbase FA Trophy Final at Wembley with a stunning strike from outside the area which turned out to be the winning goal and sent the 10,000-strong Halifax support into raptures.
