Who it fits

Key specs for this dock mount

Material: Iron

This mount uses thickened iron for its structure. Iron provides high rigidity and resistance to bending under load. This ensures your Thunderbolt dock stays firmly in place without wobbling. If you use heavy docks, this material choice offers better stability than plastic alternatives. It also supports a powder-coat finish that prevents rust and chipping during daily use.

Weight: 1.15 pounds

The bracket itself weighs 1.15 pounds. This mass adds stability to the under-desk assembly. A heavier mount resists shifting when you plug or unplug cables from your dock. When comparing laptop setups, consider if your desk surface can support this weight plus the dock. This weight is moderate for a metal rack and helps keep the unit secure.

Color: Black

The mount is finished in black. This color matches most standard desk surfaces and electronic equipment. It helps the hardware blend into your workspace rather than standing out. If you have a dark desk, this option reduces visual clutter. White is also available if your setup features lighter furniture or a minimalist aesthetic for a different look.

Connectivity: Thunderbolt 4, Thunderbolt 3

This mount is designed for Thunderbolt 4 and Thunderbolt 3 docks. It does not affect data speeds but physically accommodates these specific dock models. You must ensure your dock is compatible with these standards. This compatibility is crucial for users who need high-bandwidth connections for portable monitors or external storage attached to their laptop setup.

Design and Build Details

The listing describes this mount as an iron rack weighing 1.15 pounds. It uses thickened iron with a powder-coat finish. This finish prevents rust and chipping over time. You can choose between black or white colors. The structure is open, which allows air to flow freely around your dock. This design helps keep the Thunderbolt 4 or 3 dock cool during use. It also keeps the ports accessible without removing the mount.

According to the listing, the mount includes four black silicone blocks. These blocks ensure the surface is smooth to touch. They also protect the bottom panel of your dock from scratches when you slide it in and out. The open design ensures optimal cooling and easy access to all ports. You can mount it under a desk or on a wall. The package includes 12 screws for a secure attachment. You can also use double-sided mounting tape if you prefer a different installation method.

This layout helps eliminate clutter on your desk surface. It keeps the dock and power cable stable and secure. The design avoids the risk of the dock falling over, which is useful if you have small children or pets nearby. The mount is recommended for desk use. It allows your dock to push into place easily. This makes it simpler to plug and unplug devices. The sturdy build ensures your equipment stays in place while you work.

Setup and Daily Use Guide

You install this mount using either screws or double-sided tape. The listing includes twelve screws for a secure attachment to your desk or wall. If you prefer a non-invasive method, you can apply the tape to the bracket’s screw holes. You then attach the bracket to the dock and stick the assembly under the table. This dual option lets you choose the method that best fits your workspace needs.

The mount is designed specifically for CalDigit TS4 and TS3 Plus docks. It supports both Thunderbolt 4 and Thunderbolt 3 connections. The open design allows air to flow freely around the unit. This airflow helps manage heat during long work sessions. You can access all ports easily while the dock is mounted horizontally.

In daily use, the mount keeps your dock and power cable stable. The thickened iron construction prevents wobbling. Four black silicone blocks line the contact points. These blocks protect the dock’s bottom panel from scratches when you slide it in or out. The powder-coat finish ensures the iron does not rust or chip over time.

This setup eliminates clutter by removing the dock from your desk surface. It creates a clean look and reduces the risk of the dock falling over. This is particularly useful if you have children or pets nearby. The mount holds the dock securely without scratching the surface. You get a tidy workspace with reliable access to your connections.

Before You Buy This Mount

This holder is designed specifically for CalDigit TS3 Plus and TS4 docks. You must verify your dock model before purchasing, as it will not fit other brands or sizes. The mount secures the dock horizontally, keeping ports accessible and improving airflow through its open design. You should check your desk thickness to ensure the included screws or double-sided tape adhere properly. The iron construction adds minimal weight but requires a stable surface to prevent vibration. If you use a different Thunderbolt dock, this product is not suitable. You may need additional cable management clips if your power cable is bulky, as the mount focuses on the dock body. This accessory fits well in setups where desk space is limited. It complements portable monitor hubs by reducing clutter under the primary workspace. Ensure your desk material can support the weight and mounting method. This is a specialized solution, not a universal holder.

Check before you buy

• Verify your dock is a CalDigit TS3 Plus or TS4 model.
• Check your desk thickness to ensure screw or tape mounting works.
• Confirm the mount fits your specific dock dimensions and weight.
• Ensure you have space under the desk for horizontal placement.
