Huddersfield Town frustrated hosts Wrexham in a tense game of few chances between two of League One's promotion hopefuls.
Phil Parkinson's Wrexham were unable to break down the Terriers' defence, while Michael Duff's side were equally frustrated at the other end.
The clearest opportunities for both sides came in the second period, with Wrexham striker Paul Mullin heading over late on to sum up their display.
Huddersfield's Bojan Radulovic earlier saw his 81st-minute effort blocked by home goalkeeper Arthur Okonkwo.
Wrexham stay second in the table, but are now four points behind leaders Birmingham City, while Huddersfield rise a place to fifth.
Wrexham manager Phil Parkinson said:
"It was a hard-fought draw. We were the better side, dominated for long periods and couldn't quite get the moment [to score].
"I thought we got Elliot [Lee] on the ball in some good positions and we moved the ball round well.
"They changed their shape, they flattened out the midfield in the second half and credit to them for that, and it became an even tighter game - but it was always going to be like that, no quarter given."
