Wrexham goalkeeper Joslain Mayebi played the roles of villain and hero as the visitors drew at Ebbsfleet in the Blue Square Bet Premier.
The Welshmen went ahead through Johnny Hunt's left-footed strike following good work by Dean Keates in the first half.
Fleet levelled when Mayebi's error allowed Liam Enver-Marum to score from 20 yards, as the keeper dropped a simple ball at the feet of the United man.
But Mayebi made amends when he saved Moses Ashikodi's late penalty, after Neil Ashton was judged to have handled on the edge of the box as ball bounced up to hit him.
The game though was marred by a nasty injury to Wrexham centre half Mark Creighton, who landed awkwardly and seriously damaged his knee.
Referee: Graham Horwood (Luton)
