hi the chubb 3U115 and the union 2101 are exactly the same lock under different names, though curtains do differ slightly, but pick and fit identical, its also the same as the yale 562.
the 135 is a 110 with a latch added.
the 3U114 is exactly the same as the union2134, the yale bs and the ingersol bs.
the lock u described to me on the pm sounds like the 3G220 as this is the only chubb you measure along and then down to drill, though the detainers in a 110 may look like you drill down, ive put the drill point for a 110 in pm.
