GE & Hotpoint Refrigerator Door Shelf Retainer Bar End Cap Parts — Models & Compatibility

That little plastic cap on your refrigerator door shelf retainer bar might seem insignificant until it cracks off and your shelf sags or falls. This WR2X8345 end cap keeps the retainer bar properly secured, preventing door shelf collapse. This hub covers GE, Hotpoint, and RCA refrigerator models that use this specific end cap design — from the TBX series through CTX models.

Is This the Right Part for Your Model?

Before ordering, you'll need to verify your model number. On most GE and Hotpoint refrigerators, look inside the fresh food section along the upper left or right wall. You'll find a white or silver label with your model number printed on it. Some models have the label on the interior ceiling. Cross-reference your model number with the compatibility list below — this WR2X8345 end cap fits over 50 different GE and Hotpoint refrigerator models manufactured primarily in the late 1990s through early 2010s.

About This Replacement Part

The WR2X8345 door shelf retainer bar end cap is a small but critical component that secures the metal or plastic bar running across your refrigerator door shelves. These end caps snap onto the ends of the retainer bar, holding it firmly against the door liner. Over time, the plastic becomes brittle from temperature cycling and impact from bottles or jars. When an end cap cracks or breaks off completely, the retainer bar loses its anchor point. This causes the entire shelf assembly to tilt, sag, or even fall out when you open the door. You'll notice items sliding off or the shelf sitting at an angle.

This replacement part supersedes older part numbers AP2060073, PS298977, WR02X8345, and WR2X7617 — so if you've found any of those numbers in your research, this WR2X8345 is the updated version that fits the same mounting points. The cap installs by snapping into place on the retainer bar end, requiring no tools. Most owners replace both end caps at once since they typically wear at similar rates.

Compatible Model Series

This end cap works across multiple GE refrigerator series including TBX (top-mount models like TBX18TAZERAD and TBX21IABLRWW) and GTS series (side-by-side configurations). Hotpoint owners with CTX series refrigerators — particularly CTX16 and CTX14 models in both RAD and RWH color finishes — will find this is their correct replacement part. The design remained consistent across these product lines, making this a reliable cross-brand solution for door shelf retention issues.

Installation Overview

Replacing a door shelf retainer bar end cap takes about 5 minutes per shelf. First, remove any items from the affected door shelf. Carefully pull the shelf assembly forward to access the retainer bar. If the old end cap is still partially attached, pry it off with your fingers or a flathead screwdriver. Clean any plastic debris from the bar end. Align the new WR2X8345 cap with the retainer bar end and press firmly until you hear or feel it snap into place. Reinstall the shelf assembly, ensuring it sits level and secure. Test by placing weight on the shelf — it shouldn't tilt or shift.

Common Questions

Can I use this on just one end, or should I replace both? You can replace just the broken one, but since both caps are the same age and subjected to identical wear, the second one often fails within weeks or months. Replacing both prevents a repeat repair.

Will this fit my bottom door shelf? Yes, if your model number is listed as compatible. Most GE and Hotpoint refrigerators use the same end cap design across all door shelves on a given model.

The retainer bar itself is bent — will this cap fix it? No, if the metal or plastic bar is warped or cracked, you'll need to replace the entire retainer bar assembly, not just the end cap.
