CENTRIOS CE-238 - Deadlatch for CEB100 Series

Two backsets are offered on the CE-238: 2-3/8 inch and 2-3/4 inch. Measure from the edge of the door to the center of the 2-1/8 inch bore. Most commercial openings prepped to standard 161 prep run 2-3/4 inch, while 2-3/8 inch is the common residential and light-duty prep. Order the one that matches the hole already in the door, not the one on the lock you are removing from a different opening.

No. The Falcon Q330-203 is a square corner deadlatch faceplate with a 2-3/8 inch backset built for the Falcon Q330 W Series, so it is matched to that lock body rather than to a CEB100. The deadlatch made for the CEB100 cylindrical lock is the CENTRIOS CE-238, which comes in 2-3/8 inch and 2-3/4 inch backsets with either a square corner or round corner latch face. The two parts look alike in a bin because both are square corner cylindrical deadlatches, but the lock chassis they serve is different, so order by the lock you are servicing.

Two finishes: 626 satin chrome and BSP black suede powdercoat. Both are available in either backset and in either corner style. 626 is the standard commercial satin chrome that will sit alongside the bulk of institutional lever and exit hardware; BSP is the matte black option for openings already specified in black. Match the latch face to the lever trim, since the faceplate is the piece that stays visible on the door edge.

It is a deadlatch. Alongside the main latchbolt there is a smaller deadlocking plunger that rides on the strike lip and holds the bolt from being retracted once the door is closed. That is what stops a card or shim being slipped between the door and frame to loose-latch the opening. It only works if the strike is aligned so the plunger lands on the strike face rather than dropping into the strike opening with the bolt, which is the single most common install error on this kind of latch.

Yes. The CE-238 is sold on its own as the deadlatch component for the CEB100 Series, so a bent, worn, or wrong-backset latch can be swapped without replacing the smart lock chassis or re-doing the door prep. For a property manager standardizing a building, it also means one CEB100 model can be fitted to both 2-3/8 inch and 2-3/4 inch prepped doors by ordering the matching latch.

No handing to specify. What you do specify is backset (2-3/8 or 2-3/4 inch) and corner style (square or round), and the finish. Cylindrical deadlatches of this type are reversible in the field by rotating the latchbolt, so one part covers both left and right hand doors. That makes it a practical part to stock on a truck or in a maintenance shop.

The Falcon Q330-203 is a square corner deadlatch faceplate, so its corners will not follow a mortise that was routed with a radius. Setting a square face into a round prep leaves gaps at the corners and usually means filing the pocket. Where the existing prep is radiused, the CENTRIOS CE-238 deadlatch is offered with a round corner latch in both 2-3/8 inch and 2-3/4 inch backsets, which matches a routed edge prep without rework. Confirm the corner radius of the existing plate before you pull the old latch.

It is a commercial-duty part, built for the CEB100 Series cylindrical lock used on commercial openings. That is the traffic it is intended for, so it is the right latch for an office, multi-family common door, or institutional corridor opening rather than a residential-only spec.

The CENTRIOS CE-238 deadlatch is offered in 626 satin chrome and in BSP black suede powdercoat, across both the 2-3/8 inch and 2-3/4 inch backsets and both latch face corners. The Falcon Q330-203 is identified as a square corner deadlatch faceplate at 2-3/8 inch backset in the Q330 Series. If the building is being carried in a dark finish rather than satin chrome, the CE-238 in BSP is the one that keeps the visible latch face on the door edge consistent with the rest of the openings.
