Instead of a power strip sitting on the floor with cables radiating in every direction, everything goes inside a lidded box. The outside looks clean; the inside handles all the cable chaos. ## How a cable management box works The basic design is consistent across most models: 1. Mains power cable enters through a slot in the back or side of the box 2. Power strip sits inside the box connected to the mains cable 3. Device power cables (monitor, laptop, speakers) exit through separate slots in the front or sides 4. The lid closes over everything, hiding the power strip, adapters, and excess cable length The box is then placed on the floor under or beside the desk, or on a desk shelf if space allows. Some models include a cable tray on top for keeping additional cables neatly routed outside the box. ## Types of cable management boxes For most home office setups, a floor-standing or under-desk-mounted box is the most practical choice. It handles a full-size power strip and the excess cable length for every device on the desk. ## What to look for when buying **Size:** The box must fit your power strip with room for cables inside. Measure your power strip length before buying — most strips are 30–35 cm long. Look for a box interior length of at least 35 cm. Width should accommodate the strip width plus the cable plugs at each outlet. **Slot position and count:** Look for multiple cable slots at different points (front, back, sides). More slots give you more flexibility in routing cables. Slots should have smooth edges — sharp edges wear through cable insulation over time. **Ventilation:** Power strips generate heat. A box with ventilation holes or mesh panels is safer than a fully sealed box. Avoid sealed boxes with no airflow. **Material:** ABS plastic is standard and fine. Look for flame-retardant material — check the product listing; reputable brands will specify this. **Lid type:** Hinged lids are more convenient than fully removable lids. Check that the lid can be opened without moving the box, since you will need to access it when swapping equipment. ## How to set up a cable management box 1. **Place or mount the box** — decide whether it goes on the floor, under the desk surface, or on a shelf 2. **Thread the mains cable** through the back slot first 3. **Place the power strip** inside the box and connect it to the mains cable 4. **Thread device cables** in through the appropriate slots 5. **Arrange excess cable** inside the box — fold it loosely, do not coil tightly around itself 6. **Close the lid** and check that no cables are pinched at the slot edges ## Positioning the cable management box The cleanest result comes from mounting the box directly under the desk surface, with device cables exiting through the front slot and running straight up to the desk. This keeps all cables off the floor and out of sight from every angle except directly below the desk. For the full under-desk cable routing approach, see the [under-desk cable management guide](/under-desk-cable-management/). ## Cable management box vs cable tray A cable management box and a cable tray solve different problems. A box hides a power strip and excess cable length; a tray routes cables along a path and holds them flat against the desk or wall. Most home office setups use both: a cable tray to route cables along the underside of the desk, and a cable management box at the end of that run to contain the power strip and adapters. For guidance on cable trays, see the [cable management tray guide](/cable-management-tray/). ## Common mistakes **Buying a box that is too small.** Measure the power strip first. A box that is too short means the strip cannot fit and the lid will not close. **Using a sealed box with no ventilation.** Power strips need airflow. A fully sealed box will overheat under a constant load. **Coiling cables tightly inside the box.** Tight coils create heat build-up in power cables. Fold loosely instead of coiling. **Placing the box where it gets kicked or moved regularly.** Under a desk where chair movement sweeps past it is a poor position — cables will pull loose. Position against a wall or mounted under the desk surface.
