QNAP TRAY-35-BLK01 3.5" HDD Tray with Key Lock

Overview

The TRAY-35-BLK01 is a replacement or spare 3.5" hard drive tray designed for compatible QNAP NAS enclosures. It includes a key lock mechanism with two keys, letting you physically secure individual drives in multi-bay systems — a straightforward way to restrict unauthorized drive removal in shared environments such as server rooms, co-location racks, or office NAS deployments. If you are expanding a QNAP NAS, replacing a damaged tray, or stocking a spare, the TRAY-35-BLK01 is the direct replacement path rather than sourcing a generic alternative that may fit loosely or lack the locking tab.

Compatibility

This tray is designed for QNAP NAS enclosures that use the standard 3.5" black tool-less or keyed tray format. Verify your specific enclosure model against the QNAP compatibility list before ordering — tray designs vary across QNAP product generations and not all enclosures share the same bay interface. Consult the QNAP NAS catalog to confirm your enclosure series. Compatible enclosures typically fall within the QNAP Tower and Rackmount NAS families that ship with this same black tray format. If your system shipped with a differently shaped or colored tray, check your enclosure documentation for the correct tray SKU.

Installation Notes

Seat the 3.5" drive into the tray using the side-mounting screw holes before sliding the assembly into the bay. The key lock engages once the tray is fully inserted — keep one key accessible and one in secure storage. No additional tools are required for the bay insertion itself. Two keys are included; if keys are lost, replacement is not possible without replacing the tray, so store the spare deliberately.
