NOMADS marked the passing of vice-chairman Brian Morris in the best possible manner with a victory that moves them within touching distance of safety.
Only a Sam McNutt strike separated the strugglers, but the gap in class was wide on a blustery afternoon on Deeside.
Quay had an early escape when referee Kevin Parry failed to penalise goalkeeper Paul Pritchard for a blatant shove on Graham Evans in the box.
Salt was rubbed into the away side’s wounds in the 18th minute when lively left-winger McNutt, who had earlier gone close with a free-kick, scored direct from a corner.
With the wind at their backs the hosts were always quick to try their luck from distance, with the excellent Danny Forde testing Andy Mulliner.
Caersws had a glorious chance to equalise before the break when Neil Mitchell broke clear, but the striker could only drag his shot wide.
And that was a close as the third-from-bottom Bluebirds came as Nomads grew in confidence in the second half.
