TownSteel DBDI-62 626 – Frequently Asked Questions

1) Does the TownSteel DBDI-62 deadbolt come with a cylinder core?
No core is included. The DBDI-62 is built to accept a small format interchangeable core (SFIC), 6 or 7-pin, Best "A" keyway, and the core is sold separately. Order the cores alongside it, or pull them from your existing Best A keyway system so the deadbolt keys into the master key setup you already run.
2) What does double cylinder mean on this TownSteel deadbolt, and where can I use it?
Double cylinder means a key cylinder on both sides, no thumbturn. Nobody gets out through that door without a key, which is why it gets specified next to glass or sidelites where a thumbturn could be reached through broken glazing. That same feature makes it restricted on required egress doors in many jurisdictions, so check your local code and occupancy before you put it on an exit. If you need key outside and turn inside, you want a single cylinder deadbolt instead.
3) Is the TownSteel DBDI-62 deadbolt heavy duty enough for a commercial entrance?
It's a Grade 1 heavy duty commercial deadbolt, which is the top ANSI/BHMA tier and the one written into most commercial and institutional specs. The housing is tamper resistant solid brass, one piece, so there's no seam to pry at the exterior face. Grade 1 is what you want on a main entry, a stairwell, or any opening taking daily traffic and abuse.
4) Will a 2-3/4 inch backset deadbolt line up with my existing bore?
The DBDI-62 is a 2-3/4 inch backset deadbolt, measured from the door edge to the center of the cross bore. That's the standard commercial backset; 2-3/8 is the other common one and is typical of residential and lighter-duty prep. If your existing hole is drilled at 2-3/8, this one will not drop in without redrilling the door and edge bore. Measure before you order.
5) Can I standardize a building on the DBDI-62 and key it to my existing master key system?
Yes, if your system runs Best "A" keyway small format cores. The deadbolt takes a 6 or 7-pin SFIC in that keyway, so a facility already on Best A can pin cores to its existing master and grand master levels and drop them in without rekeying the lock body. For a property manager or MRO buyer, that's the point of SFIC: cores get swapped on a tenant turn in seconds, no door taken apart.
6) Do I need a separate strike or reinforcement for a commercial deadbolt like this?
Plan on the frame side of the job either way. A Grade 1 deadbolt only performs to grade if the strike is anchored into the frame or into solid backing rather than just the jamb casing. On a hollow metal frame, make sure the existing deadbolt strike prep matches the 2-3/4 inch backset location of the DBDI-62 before you start cutting.
7) What finish does the TownSteel DBDI-62 come in?
Satin chrome, BHMA finish code 626. That's the standard commercial finish and it matches 626 levers, exit device trim, and closers already hanging in most office, school, and healthcare buildings, so it blends into an existing hardware set without looking like a one-off replacement.
8) Is this TownSteel deadbolt electronic or does it need wiring?
Purely mechanical. The DBDI-62 is a keyed deadbolt with no electronics, no wiring, no power supply and nothing to tie back to an access control panel. It throws and retracts by key only, which also means it keeps working during a power outage.
