With both teams ending the game with ten men, there was space all over the pitch that the visitors made the most of.
Minutes later Luke Moore was dismissed for the hosts for an alleged elbow, with Rangers making the most of their advantage late in the half as Steve Cawley picked up on a loose Margate pass to slot home.
It could and probably should have been worse for the Blues at half-time, as Chiedozie hit the post with a sharp shot from the right.
Joao Carlos then missed an open goal from 40 yards and saw a cross from the left clip off the crossbar and away to safety.
Soon after the break the game was sealed though, with Cawley tapping home after Chiedozie’s shot cannoned off the post from the edge of the area.
Carlos was given his marching orders after pole axing Alex Osborn, but it didn’t stop Concord soaring on, as Audrius Laucys netted low from the edge of the box.
The onslaught continued, with Cawley completing his hat-trick, when he pinched the ball of goalkeeper Jordan Carey before slotting into an open goal.
Harry Phipps headed a late consolation, his first goal for the club, but it was a truly a day to forget for Margate.
