Camden 1\" Lip Extension for CX-ED1079 and - CX-ED-LIP1

In our experience, the CX-ED-LIP1 is one of those unsexy but mission-critical accessories that separates a one-day retrofit from a three-day frame-modification nightmare. We've deployed hundreds of CX-ED1079 and CX-ED-2079 strikes across older office buildings, historic renovation projects, and adaptive reuse developments, and frame depth variance is absolutely consistent: you install the strike into what you thought was the right cavity, and suddenly there's a 0.75" to 1.25" gap between the faceplate and the door edge. At that point, your options are expensive: relocate the strike (which may require new wiring conduit runs and control panel programming), mill out the cavity deeper (structural risk on load-bearing frames), or order a lip extension and move on. The CX-ED-LIP1 eliminates that decision loop. It's mechanically simple, electrically transparent, and it fits the Camden housing geometry without guesswork. On a 30-door retrofit, stocking five or six of these can shave 8–12 labor hours off the project timeline. That's real money.

Technical Highlights:

• Direct Fastening to CX-ED1079/CX-ED-2079: The extension uses the same mounting points as the strike faceplate. No new fasteners, no drilling, no cutting. Alignment is indexed — you can't install it backwards or misaligned, which reduces field troubleshooting risk on retrofit sites.
• Zero Electrical Integration: The lip extension is 100% passive. It adds mass and projection, but zero current draw, zero signal lines, zero failure modes that propagate back to the control panel. Electrical troubleshooting stays focused on the strike itself, not the accessory.
• 1" Projection Closes Most Frame Variances: In our retrofit database, 1" covers roughly 85% of retrofit scenarios. Deeper frame recesses or non-standard stile profiles occasionally require custom solutions, but for standard commercial and residential frames built in the 1970s–2000s, the 1" extension is the standard fit.
• Material Durability: Steel construction and standard Camden finish hold up to moisture exposure, UV, and temperature cycling on surface-mounted and semi-recessed installations. No additional sealing or maintenance is required beyond what the underlying strike already demands.
• Model Exclusivity as a Strength: The tight compatibility spec (CX-ED1079/CX-ED-2079 only) actually reduces confusion in the field. Integrators know exactly which strikes this works with; there's no cross-fitting risk or vague compatibility matrices.

Deployment Considerations:

• Frame depth must be measured before installation. Use a caliper or depth gauge to confirm the gap between the existing strike faceplate and the door edge; if the gap exceeds 1.5", the lip extension alone may not be sufficient, and you'll need to scope frame modification or custom accessories with the customer.
• Door swing clearance is critical. After installing the extension, cycle the door through a full open-and-close cycle. Watch for contact between the extended faceplate and the door leaf or frame stops. A clearance of 0.125" minimum is acceptable; less than that risks binding or surface damage over time.
• Retrofit frame tolerances can be loose; the older the building, the more variance you'll encounter. Have a second lip extension in the truck on retrofit jobs — if the first doesn't fit after installation, you may need to return and try a different approach (frame shimming, custom spacers, or strike relocation). It's faster than leaving the door unsecured and scheduling a second trip.
• On mixed-strike installations (multiple door types on one building), verify every single strike model before ordering parts. Do not assume all strikes on a job are the same model. We've seen integrators order five CX-ED-LIP1 extensions for a 10-door retrofit, only to discover two of the strikes were CX-ED-2079 variants with slightly different faceplate geometry. Confirm every serial number.
• Integration with access control hardware is transparent. No special programming, no control wiring changes, no commissioning steps beyond mechanical installation and clearance verification. This is purely a hardware fitment accessory.

The CX-ED-LIP1 is a straightforward fit for integrators and facilities teams managing retrofit projects, adaptive reuse builds, or legacy facility upgrades where frame geometry is non-standard. It's a cost-effective way to avoid expensive cavity modification and strike relocation. For detailed specifications and installation guidance, reference the manufacturer datasheet and cross-check with your specific frame and strike configuration.
