Schlage Commercial 38-016 Adaptor Ring Kit (2 Each 38-031), B252 in 2-1/8" Hole

The 38-016 is a trim ring kit, not a lock. It adapts a Schlage B252 deadbolt to a door bored with a 2-1/8 inch hole, and each kit ships with two of the 38-031 rings. The deadbolt itself is a separate order, so if you are specifying a new opening you are buying the B252 and the ring kit as two lines.

B250 and B500 Series Schlage deadbolts. If your building runs a mix of both series, the same 38-016 kit covers them, so the variable you have to get right on the order is finish, not series. The bore it addresses is the 2-1/8 inch cross bore, which is the standard deadbolt hole in a commercial door.

Yes, and it is worth checking before you order. These rings are finish specific and sit in plain view against the deadbolt rose, so a mismatch shows. Three finishes are made: 605 bright brass, 626 satin chrome, and 613 oil rubbed bronze. Pull the BHMA number off the lock you are working with and order the ring to match it rather than eyeballing the color.

One kit per deadbolt. The 38-016 contains two 38-031 rings, which handles both faces of a single door, since a deadbolt presents trim on the cylinder side and the turn side. Doing a floor of twenty openings means twenty kits, not forty.

38-031 is the individual adaptor ring. 38-016 is the kit number covering two of those rings in one finish. If a spec or a parts list calls out 38-031, ordering the 38-016 gets you that part in the correct quantity for one door.

Schlage builds the 38-016 as a commercial part, matched to the B250 and B500 Series commercial deadbolts. The hole it works to, 2-1/8 inches, is the same cross bore used on ordinary residential doors, so the door is rarely the limiting factor. What decides whether this is the right ring is the deadbolt series already in the door.
