D-Line Cable Management Box, Power Strip Cover, 12.75"x5"x4.5" - Small, Black Review (2026)

Who this cable box suits

This D-Line box is built for anyone who wants to hide a single power strip and the tangle of chargers plugged into it, whether that is under a desk, behind a TV stand or along a baseboard near an outlet. Its small footprint of 12.75 by 5 by 4.5 inches makes it a good fit for compact spaces where a larger cable management box would look bulky or simply not fit. Households with young children or pets are a natural audience, since an enclosed box keeps curious hands and paws away from live outlets and cords. Because D-Line specializes in cable management products rather than treating this as a side accessory, the box is built with a dedicated purpose rather than being a generic storage container repurposed for cords.

Size, materials and what fits inside

Internally the box is sized to accommodate a power strip up to roughly 10.5 to 11 inches long, which covers most compact 4 to 6 outlet strips but rules out the longer power strips with 8 or more outlets or a built in surge protector housing. The shell is made from ABS plastic that D-Line describes as electrically safe and safety tested, giving some reassurance for a product that sits directly around a mains power strip. Three cord entry and exit points sit at the rear of the box, allowing the main power cord in and the individual device cables out without needing to squeeze everything through a single gap, which helps keep the routing tidy rather than bunched at one corner.

Living with it day to day

Once installed, the box's main job is visual: instead of a nest of cords and a power strip sitting exposed on the floor or desk, everything is contained behind smooth rounded corners that are designed to blend into a home or office rather than look like a piece of electrical equipment. The click lock lid keeps the box closed during normal use while still allowing access when a cord needs to be added or swapped, which matters if the plugged in devices change over time. Because the box fully encloses the strip, it is worth leaving enough plugs unused or spaced out inside so heat from multiple chargers running at once has somewhere to dissipate, rather than packing the box to its absolute limit, since enclosed power strip boxes in general need airflow room around the plugs to avoid excess heat buildup.

How it compares with other cable boxes

Within this guide, the larger D-Line box in this same product family offers more interior space for bigger power strips while sharing the same rounded, safety tested design. The Cable Management Box 3 pack with 33 pieces takes a different approach, bundling multiple smaller boxes and cord covers rather than one central box, which suits a room with several separate outlets rather than one central strip. NTONPOWER's boxes add a built in phone holder on top, which is a useful extra for anyone who wants a charging spot visible at a glance, though that comes at the cost of a slightly bulkier shape. Against all of these, this small D-Line box remains the more minimal, purpose built option for a single compact power strip rather than a multi device charging station.

Verdict

This D-Line cable box is a straightforward, well built solution for hiding one small power strip and its cords, and its safety tested ABS construction and rounded design make it a sensible pick for homes with kids or pets nearby. The clear limitation is size: anyone running a long strip with six or more outlets, or wanting to combine a phone holder with the cable box, should look at a larger D-Line model or a rival with more capacity. For a single compact strip near a desk, entertainment unit or hallway outlet, this box does exactly what it promises without unnecessary bulk.
