D-Line Cable Management Box, Power Strip Holder - Large, Black Review (2026)

Who needs the large size specifically

This is the bigger of D-Line's two common cable box sizes, built for people whose power strip or surge protector is too long for a compact organizer. A typical use case is a desk or media console where a 6 to 8 outlet strip powers a monitor, a docking station, a lamp and a couple of chargers all at once, since that combination usually needs a strip longer than a small box can hide. Anyone who has already tried a small cable box and found the plugs still poking out the ends is the direct audience for the large version. It also suits households with young children or curious pets, since fully enclosing a power strip behind a solid plastic shell reduces the temptation to pull on cords or reach into outlets.

Size, materials and what it holds

The large D-Line box measures about 16.5 inches long, 6.5 inches wide and 5.25 inches tall, and is built from rigid black plastic with a lid that lifts or slides open for access. Inside, it is sized to enclose a power strip up to roughly 13.4 inches in length along with the cords feeding into it, leaving room for the plugs and cable bends without forcing everything to bend sharply. D-Line brands this as part of its Cable Tidy range, which is generally sold as a plain box rather than a bundle, so buyers should confirm whether cable sleeves or wraps are included separately before assuming extras come in the same package. The black finish is meant to blend into most desks and media furniture rather than stand out.

Living with it under a desk or media unit

Once installed, the box sits flat under a desk or behind a television stand and simply gets ignored, which is the entire point of a cable management box like this. Cutouts in the ends let cords pass in and out without needing to remove the lid every time a new device gets plugged in, so daily use does not involve reopening the box. Because the box fully encloses the strip, dust buildup on the outlets themselves drops noticeably compared with an exposed power strip sitting on the floor. One thing to watch is heat: packing several chargers or a laptop brick into the box along with the strip can make the enclosed space warm, so it helps to leave a little breathing room rather than stuffing every cable in as tightly as possible.

Trade-offs against the small D-Line box and rivals

Our score of 8.1 out of 10 reflects genuinely solid build quality that holds its own against most cable boxes at this price. The obvious trade-off for the large size is footprint: it takes up noticeably more floor or desk space than the small D-Line box, so anyone with a short power strip is better served by that compact version instead. Compared with the XSHEEP 3-pack in the same under-desk cable box guide, which ranked just ahead in this comparison, this single large D-Line box is a better fit for one big strip in one location, while the 3-pack spreads smaller boxes across a desk, a TV stand and a bedside table. NTONPOWER's boxes in the same guide add a phone holder on top, a feature this D-Line box does not include.

Verdict and who should pick a different size

For a single desk or media area with one long power strip, the large D-Line box is a dependable, well-built choice that solves the clutter problem without fuss. Anyone whose power strip is shorter than about a foot should buy the small D-Line box instead, since the large size will just waste space unnecessarily. People who need to manage cables in several rooms or at several spots around one room may get more overall value from a multi-box set like the XSHEEP pack, even if each individual box feels less substantial than this D-Line unit. Households with heat-sensitive chargers should leave the lid slightly ajar or pick a spot with airflow.
