This article covers アップグレードデスク下および壁取り付けホルダー Thunderbolt 4 Dock.

Overview

The JinLunar Under-Desk Mount Bracket is a purpose-built accessory for the CalDigit TS4 and TS3 Plus Thunderbolt docks. Unlike adhesive-based mounts that can fail over time, this bracket uses a screw-fastening system to secure the dock firmly under your desk. The heavy-gauge powder-coated steel frame provides long-term durability, while integrated silicone pads prevent scratches and slippage. This mount is ideal for users who want to reclaim desk space and achieve a cleaner cable management setup. The open-frame design ensures that the dock's bottom ventilation panel remains unobstructed, allowing for proper airflow and thermal performance even when mounted upside down.

Connectivity & Compatibility

This bracket is designed exclusively for the CalDigit TS4 and TS3 Plus Thunderbolt docks. It is not compatible with other Thunderbolt docks, USB hubs, or docking stations from other brands. Before purchasing, verify that your dock model matches either the TS4 or TS3 Plus. Installation requires drilling holes into the desk surface. All necessary screws are included in the package. Once mounted, the dock remains securely in place, and all ports, buttons, and cables remain fully accessible. The bracket can also be stacked if you need to mount multiple docks vertically.

Product Info

The JinLunar mount was released in late 2025 and is available on Japan for around ¥3,658. It sits in the mid-range segment of the market, offering a more permanent solution than adhesive mounts without the high cost of premium machined alternatives. The package includes the steel bracket, mounting screws, and silicone pads. Warranty coverage depends on the seller, but 's standard return policy applies for purchases made through the platform.

Best Use Cases

Creative professionals and engineers who need maximum desk space will benefit most from this mount. The CalDigit TS4 is a large dock that takes up significant real estate on a desk. By relocating it underneath, you free up valuable surface area for monitors, input devices, and paperwork. Users who prioritize a tidy workspace will also appreciate this product. With the dock secured under the desk, cables can be routed cleanly out of sight. The screw-fastening system ensures the mount stays put indefinitely, unlike adhesive mounts that may lose grip over time. However, this mount is not suitable for renters who cannot drill into their desk, or for users who frequently move their dock between locations. In those cases, a clamp-style or adhesive mount would be more practical.

Things to Consider

The most important limitation is that this bracket only fits the CalDigit TS4 and TS3 Plus. It will not work with any other dock model. Additionally, installation requires drilling holes into the desk, which may not be possible in rental apartments or on certain office furniture. While the screw-fastening system provides excellent stability, it also means that repositioning the mount after installation is difficult. Measure your desk clearance and cable lengths carefully before drilling. Thermal performance is generally good thanks to the open-frame design, but if the space under your desk is very confined or poorly ventilated, the dock may still run warmer than when placed on an open desk surface.
