Struggling Leyton Orient stretched their winless run to 11 games after being held by Chesterfield.
Lee Steele fired over for the hosts and O's skipper John Mackie also headed over from a corner.
Home keeper Glyn Garner was forced to tip over Wayne Allison's header and then forced into another memorable parry from Colin Larkin.
Gary Alexander was just inches away from heading a late winner for the O's, but both sides settled for a point.
