Ulster beat Harlequins in the snow
Powerful wing Jacob Stockdale was a threat all afternoon and scored the only try of the first half after a break by Man of the Match John Cooney and good build-up work by Sean Reidy.
Scrumhalf Cooney also landed a first half penalty to give the visitors an 8-0 interval lead and added three more after the break to end any chance Harlequins had of progressing in the competition.
The hosts did reduce the deficit after producing their best spell just after the break resulting in England prop Kyle Sinckler plunging over from close range.
Quins were not helped by the early loss of inspirational forward Chris Robshaw after he failed an HIA assessment and his England teammate Danny Care lasted only three minutes of the second half due to concussion.
The sides meet again in Belfast on Friday when Ulster will be seeking a double in a bid to stay ahead of Wasps in the Pool One table after they went down to runaway leaders La Rochelle.
