The unlikely hero for the Shaymen was rock solid centre-half Adam Quinn whose looping header from a Steve Haslam free-kick sailed over bemused Rovers keeper Ryan Clarke in the 18th minute - his third goal of the season.
It was Town ninth home success of the campaign and, despite a late rally of sorts; relegation threatened Rovers, with just one away win this term at Kidderminster last September, never seriously looked liked producing a surprise.
Veteran keeper Lee Butler was rarely threatened in the Town goal, although he did have to pull out a smart save on the half-hour to parry Paul Wanless' angled free-kick.
Town's nine-goal top scorer John Grant tested Clarke with a fierce drive after an incisive through ball from Tyrone Thompson in the first period with the hosts only other meaningful chance in the opening 45 minutes falling to ex-Rovers' schemer Martin Foster, who blazed over a shot.
The stop-start action continued after the break with Matt Doughty and Grant off target with chances for the hosts, while at the other end, Guy Madjo and Julian Alsop were kept in check by the excellent Quinn and Greg Young.
Grant spurned a great chance to seal the win on 71 minutes, but fired over following Danny Forrest's inviting pass. Three minutes later he hit another opportunity straight at Clarke.
Rovers' best moment arrived towards the end of the game with a super free-kick from loan star Jonathan Hayes flashing just wide minutes from time.
Portuguese substitute Bruno Teixeira then spurned a golden change to claim a shock point for the visitors three minutes form time when he steered the ball wide of the advancing Butler after Hayes' magical run dissected the Town rearguard.
