CENTRIOS CE-COVERPLATE-626-1 – Frequently Asked Questions
1) Do I still need the drill jig if my door already has a 161 prep?
Yes, that's exactly the case it's built for. A 161 prep gives you the 2-1/8 inch cross bore and the latch bore, but it does not include the two 5/16 inch holes above and below the bore that a Centrios cylindrical lock needs. The jig indexes off the existing prep and puts those two holes at 12 and 6 o'clock.
2) Is the Centrios drill jig a tool I keep, or a one-time part that installs in the door?
It's a reusable installer's tool, not door hardware. Nothing about it stays in the opening once the holes are drilled, so one jig covers a whole building's worth of Centrios cylindrical lock installs.
3) What size drill bit do I need with the Centrios CE-DRILL-JIG?
A 5/16 inch bit. The jig guides two 5/16 inch holes, one at 12 o'clock and one at 6 o'clock relative to the existing 161 bore. The bit itself is a separate purchase.
4) Will the Centrios drill jig work for mortise lock prep?
No. The CE-DRILL-JIG is set up for cylindrical lock installation on a 161 bored prep. A mortise opening uses a routed pocket and a completely different face prep, so this jig has nothing to index against.
5) Is this jig meant for commercial openings or residential doors?
Commercial. The CE-DRILL-JIG is catalogued for commercial use and is tied to 161 prep openings, which is the standard commercial cylindrical prep, not a residential bore pattern.
6) How many versions of the Centrios drill jig are there?
One. The jig is sold as a single model, CE-DRILL-JIG, with no size, hand, or finish options to pick.
