The "3034" and "3034H" are internal part designation that LCN uses to specify regular (3034) and hold open (3034H) rollers.
All the rollers are not the same, it is dependent on closer model AND where applicable, if closer has a hold open track.
So when ordering a roller you have to specify the closer model with either the 3034 or 3034H to be sure to get the correct roller. Example -Part # 2030-3034H - is a hold open roller for the 2030 series closer.
