Schlage 12-633 626 – Frequently Asked Questions
1) Will the Schlage 12-633 latch bolt fit my B600 deadbolt?
The 12-633 is the OEM replacement latch for Schlage B600, B700, and B800 Series deadbolts, so it drops into any of those three families. What it will not fit is a B-series deadbolt prepped for a different backset: the 12-633 is a 5 inch backset latch, meaning the center of the cylinder hole sits 5 inches from the door edge. Measure that distance on the door before ordering, because the standard commercial backsets are 2-3/8 and 2-3/4 inches and a 5 inch latch is the extended-backset part.
2) Will the 12-633 latch face plate cover my existing mortise in the door edge?
The face on the 12-633 measures 1-1/8 x 2-1/4 inches with square corners. If the old latch came out of a square-corner pocket of that size, the new one seats flush with no rework. If your door edge is routed for a radius corner face, the square face will not sit right in the pocket, and you either need to file the corners of the mortise square or use a radius corner latch instead.
3) Is the Schlage 12-633 the whole deadbolt or just the latch part?
Just the bolt assembly. The 12-633 is the replacement latch bolt that goes in the door edge and throws into the strike, not a complete lock. The cylinder, thumbturn, trim rings and strike stay as they are, which is the point of the part: when the bolt binds or wears you replace the bolt, not the lock.
4) I need a latch for a Dexter or Deltana lock, not a Schlage. Is the 12-633 the right part?
No. The 12-633 is built for Schlage B600, B700, and B800 Series deadbolts and nothing else. For a Dexter C1000 Series lock, the Dexter C1000-DL deadlatch is the matching part. For a Deltana cylindrical lock, Deltana lists Grade 1 regular latches by backset and function: G1RLE238 and G1RLE275 for entry at 2-3/8 and 2-3/4 inch backsets, G1RLP238 and G1RLP275 for passage/privacy at the same two backsets. Latch bolts are not cross-brand parts; the tailpiece and case geometry are specific to the lock.
5) What is the difference between the Schlage 12-633 deadbolt latch and the Deltana G1RLE275 regular latch?
They serve different lock types. The Schlage 12-633 is a replacement deadbolt latch bolt for B600, B700, and B800 Series deadbolts, with a 5 inch backset and a 1-1/8 inch by 2-1/4 inch square corner face. The Deltana G1RLE275 is a Grade 1 regular latch with an entry function on a 2-3/4 inch backset, so it is the spring latch that retracts with a knob or lever, not a deadbolt bolt. If the door has a separate deadbolt above a keyed knob, the 12-633 addresses the deadbolt and a regular latch addresses the lockset below it.
6) The deadbolt latch measures 2-3/8 inches from edge to center, not 5 inches. What latch fits that backset?
The Schlage 12-633 is built for a 5 inch backset and will not reach a bore prepped at 2-3/8 inches. For a 2-3/8 inch backset, the Deltana G1RLE238 is a Grade 1 regular latch with an entry function, and the Deltana G1RLP238 is the same 2-3/8 inch backset in a passage/privacy function. Measure from the edge of the door to the center of the bore before ordering, since backset is the one dimension that decides whether the latch lands in the hole at all.
7) Can I use a Dexter C1000 deadlatch in place of the Schlage 12-633?
No. The Dexter Grade 1 Deadlatch is built for the Dexter C1000 Series cylindrical lockset, while the Schlage 12-633 is a certified Schlage part matched to B600, B700, and B800 Series deadbolts. The two are also different bolt types: a deadlatch is the spring latch with a deadlocking plunger used in a knob or lever, and the 12-633 is the throw bolt in a deadbolt case. Replacement latch bolts follow the lock body they were made for, so the series on the existing lock decides the part.
8) What finish should I order the Schlage 12-633 in to match the rest of my hardware?
Four finishes are made: 605 bright brass, 612 satin bronze, 613 oil rubbed bronze, and 626 satin chrome. Match the ANSI number stamped on or specified for the existing deadbolt rather than eyeballing it, since 612 and 613 both read as bronze on a door but are visibly different next to each other. Only the face plate shows once the latch is installed, so that is the piece that has to agree with the rest of the door.
9) Can I use the 12-633 to convert a standard backset Schlage deadbolt to a 5 inch backset?
Yes, within the B600/700/800 family, provided the door is bored for it. The 12-633 is the 5 inch backset latch for those series, so swapping it in gives you the longer reach from the door edge. But the bolt has to line up with the existing cylinder hole and the strike in the frame. If the door is bored at 2-3/8 or 2-3/4 inches, changing latches alone will not move the hole, and you are looking at re-boring the door and relocating the strike.
10) Do I need a deadbolt latch or a spring latch for a door that has to stay latched when closed?
Two different parts. The 12-633 is a deadbolt bolt: it only moves when someone turns the key or thumbturn, and it does not retract on its own when the door shuts, so it is for securing a door that is deliberately locked. If you need the door to catch and hold every time it closes, you want a spring latch or deadlatch instead, like the Dexter C1000 Series deadlatch or a Deltana Grade 1 regular latch. Many commercial openings run both: a latchset for everyday closing and a B-series deadbolt above it for security.
11) Is there a keyless option instead of repairing the existing Schlage B-series deadbolt?
Yes, if the goal is to eliminate keys rather than restore the existing hardware. The Lockey M230 is a mechanical keyless digital combination deadlocking spring latch lock with an adjustable backset, fitting doors 1-1/8 inch to 2 inch thick, and it replaces the whole lock with a pushbutton unit. The Schlage 12-633 takes the opposite approach: it is the certified OEM latch bolt that returns an existing B600, B700, or B800 Series deadbolt to service, keeping the cylinder and key system already in place across the property.
12) Is a stainless steel latch bolt worth it for a high traffic commercial door?
The 12-633 is stainless steel and is a commercial-rated part, which is what you want on an entrance cycling all day: the bolt is the piece taking the wear every time someone throws it, and stainless holds up against the corrosion you get on an exterior opening. For a facilities team standardizing a building on Schlage B-series deadbolts, stocking a couple of these in the building's finish is the usual move.
13) Is the Schlage 12-633 a genuine Schlage part or an aftermarket copy?
Certified Schlage OEM. The 12-633 is the factory replacement latch bolt for the B600/700/800 Series, built to the same geometry and tolerances as the one that shipped in the lock, which is why it drops in without shimming or filing the mortise. For institutional and MRO buyers who have to keep the original manufacturer's parts in a building, this is the part number to stock.
