Grimsby Town have signed former Hartlepool defender Dan Jones and ex-Dagenham & Redbridge forward Ashley Chambers on one-year deals.
Jones, 21, made 12 appearances for Hartlepool last season, but was released by the club in May.
Chambers played in 39 games for the Daggers last term, but could not help them avoid relegation from League Two.
The 26-year-old has previously played for Grimsby, scoring two goals in four games during a loan spell in 2010.
