James Henry grabbed a first-half double as Aldershot beat 10-man Altrincham at the EBB Stadium.
Henry put the hosts in front with a 26th-minute finish and was swiftly on the scoresheet again with a strike four minutes later.
A foul on the former Oxford man soon after saw a yellow card shown to Tom Crawford, who was subsequently given his marching orders with 12 minutes to go following a challenge on Tyler Frost.
Jake Bickerstaff then pulled a goal back late on, but Altrincham were unable to salvage anything.
Aldershot rise a place to 17th in the National League table, now four points clear of the relegation zone, while Altrincham stay 10th.
