That means that Fax coach Richard Marshall will be able to pick Salford players not selected by Red Devils coach Ian Watson, himself a former Salford halfback.
The deal will replace last season’s arrangement with Hull Kingston Rovers.
“I think it’s an arrangement that can benefit both teams,” said Marshall, according to the Halifax Courier.
“We’re running with a squad of 24 players next season, and four of them are under 20 and relatively inexperienced at Championship level.
“If you factor in two or three injuries at any one time, you can see how important it is that we give ourselves some options.
“The situation for our players is the same as always; if we have a player who is killing it in the reserves, I will always look at them first.
“But dual registration can work for Championship teams; look at Featherstone last year, with three or four Leeds players coming into their team at crucial times.
“Salford are probably in a position where they’re going to be sitting down players each week and they also have some younger players who are contracted to them with nowhere to play at the moment.
“They’ve some big, tough middle unit players and some talented outside backs.”
