Hendon slipped to a third consecutive league defeat on a damp afternoon at Silver Jubilee Park.
Thomas Leak opened the scoring just after the half-hour mark with a tap in at the far post and Tobias Holmes doubled the lead seven minutes later with a similar finish to give the visitors a 2-0 lead at the break.
Hendon improved after the break but were unable to get back into the game before Leroy Lita completed the scoring with a precise finish in second half stoppage time.
