Chesterfield secured fourth place in the National League table with a 4-0 win over Wealdstone.
The Spireites took the lead 11 minutes before halftime when Paul McCallum converted a penalty after Liam Mandeville was brought down.
They increased their lead four minutes into first-half stoppage time when Mandeville headed in Colclough’s cross.
Wealdstone’s hopes were dashed again 13 minutes later when Sam Habergham turned the ball into his own net while attempting to prevent Andrew Dallas from getting to Colclough’s cross.
Colclough added the finishing touch himself with a delicious 77th-minute chip after racing from halfway to complete a good night’s work.
