LiftMaster K75-38330 Rear Housing Assembly for CAPXL and CAPXLV
The LiftMaster K75-38330 rear housing assembly is the main rear enclosure service part used on select CAPXL and CAPXLV connected access systems. The rear housing supports the physical structure of the unit and helps keep the display assembly, board assemblies, wiring harnesses, lock hardware, and field wiring protected and properly aligned. On outdoor entry systems, housing damage can cause more than a poor appearance. A bent or cracked cabinet can create water intrusion, strain the faceplate, pull on connectors, or prevent the front door from closing evenly. K75-38330 is used when the back section of the unit needs to be restored without replacing the entire access control system. Fitment should be verified carefully because similar LiftMaster entry systems may use different cabinet shells.

Technician Note
When the rear housing is damaged, check the faceplate, touchscreen/display assembly, power/internet board, control board, cables, lock hardware, grounding, and field wiring before reassembly. Cabinet repairs often reveal secondary damage.
Before Ordering
- Confirm the system is CAPXL or CAPXLV and not another LiftMaster entry series.
- Match K75-38330 to the exact parts diagram for the installed model.
- Inspect hinge, lock, gasket, display, and board mounting areas before ordering related parts.
- Check for water intrusion or corrosion inside the original cabinet.
- Plan for a qualified technician if field wiring or power connections must be removed.
Professional Advisory
A damaged access control enclosure can expose wiring and electronics to moisture. Do not energize a wet or compromised unit. Have a qualified access control technician inspect and repair the system when cabinet damage is severe.
Product Questions & Answers
Does K75-38330 fit both CAPXL and CAPXLV?
K75-38330 is commonly listed for CAPXL and CAPXLV rear housing assembly replacement, but the installed model and parts diagram should still be checked.
Is this the same rear housing used on EL2000SS?
No. EL2000SS uses different cabinet parts. K75-38330 is for CAPXL/CAPXLV-style connected access systems.
Why would a rear housing assembly need replacement?
It may be needed after impact damage, vandalism, corrosion, poor mounting, stripped hardware points, or weather-related enclosure failure.
Does this include the control boards or display?
Treat it as a rear housing assembly unless the supplier specifically lists additional components. Electronics and display assemblies are normally separate service parts.
Should the faceplate be replaced at the same time?
Replace the faceplate only if it is bent, cracked, misaligned, or damaged. Always check the front assembly for proper fit before reusing it.
