What’s up with the instructions for the Schlage Plymouth BE365 lock? They say it’s compatible with 1.5″ bore holes, but that’s clearly not true. The 2-1/8″ collar is NOT removable. Clearly a copy-paste error by an eager graphic-design intern LOL. Went with Kwikset’s Powerbolt 250 instead. It has a removable collar. Worked like a charm! Though I did need to enlarge the deadbolt hole slightly with a rasp bit. Just move it around in a circle, trying your best to keep the bit parallel with the hole.
