Jacob, who joined Dulwich Hamlet at the start of the season, has made 25 appearances for the club this season., the last of which came as a second half substitute in the London Senior Cup victory over London Bari.
So far this season Jacob has scored seven goals but has been hampered by injury during the course of the campaign.
He joins Jamie Mascoll at Hayes Lane with the Wands in the thick of the promotion race, only kept out of the playoff places on goal difference.
Dulwich Hamlet wish Jacob every success with Cray Wanderers and look forward to seeing him back in a Pink and Blue shirt before too long.
