The Von Duprin ECAP.105 is the OEM endcap kit for the Von Duprin Guard-X 2670 exit alarm lock, documented in the Von Duprin Guard-X 2670 Exit Alarm Lock Service Manual (doc 108462). The kit contains one endcap and two 10-24 x 1/4" UFPHMS (Undercut Flat Point Hex Machine Screw) fasteners that secure the endcap to the device housing. Finish must be specified at time of order to match the installed Guard-X 2670 device finish.

The endcap terminates the 2670 device housing at the end of the unit, closes the internal cavity from dust and physical intrusion, and provides a finished appearance. When the endcap is damaged, broken, or missing - from impact, vandalism, or forced tamper - the device housing is open at the end. Internal electronic components and wiring connections become exposed and vulnerable to moisture ingress, physical interference, and debris accumulation. The ECAP.105 kit restores the sealed housing condition without replacing the complete device.

What the Von Duprin Guard-X 2670 Is

The Guard-X 2670 is Von Duprin's battery-powered exit alarm lock for single door "Emergency Exit Only" applications. This is not a panic exit device in the 98/99 Series sense - it does not have a pushbar that actuates a mechanical latch. Instead, the 2670 is a surface-mounted alarm lock that mounts on the door and frame, monitors the door for unauthorized opening, and activates a 100dB+ alarm when the protected door is opened without authorization.

The "Emergency Exit Only" label on the device face is the signal to occupants: this door is for emergency egress only, not for routine passage. When the door is opened, the alarm activates immediately. The device uses battery power - no hardwired connection required - making it installable on any secondary exit door regardless of whether electrical infrastructure is in place at the door.

The 2670 is available in English, Spanish, and French alarm sign versions (SIGN.1001, SIGN.1002, SIGN.1003) to match the required language for the facility and jurisdiction. The PCB Kit (PCB.10018/10019/10020, corresponding to English/Spanish/French) provides the field-replaceable printed circuit board and alarm electronics. The Lightpipe Kit (PIPE.101) provides the light transmission element for the status indicator. The ECAP.105 endcap kit (this product) and the BRKT.121 bracket complete the 2670 parts catalog.

Von Duprin 2670 Series Endcap: Finish and Application Context

The endcap ships in a finish-specific version because the Guard-X 2670 device is offered in standard architectural commercial finishes - matching the endcap to the device body finish is a visual specification requirement in architectural applications. Common 2670 finishes include US28 (satin aluminum), US26D (satin chrome), and US32D (satin stainless steel). Ordering the wrong finish creates a mismatched appearance on the device face.

The 10-24 x 1/4" UFPHMS fasteners in the kit are the specific thread and head format required for the 2670 housing mounting points. UFPHMS screws have an undercut head profile designed to sit flush against the housing surface without protruding, which matters both aesthetically and functionally - a protruding screw head on the endcap creates a snag point that can catch hardware, clothing, or objects passing close to the door edge.

The 2670 is also offered in a double-door variant - the Von Duprin 2609 - for applications where both leaves of a pair need simultaneous alarm monitoring. The ECAP.105 endcap kit covers the single-door 2670 configuration documented in the Guard-X 2670 and 2609 Service Manual (doc 108462).
