D-Line Medium Cable Raceway Accessory Pack, Join 1.18in x 0.59in Cord Cover Lengths, 10 Accessories Included, Hide Cords Around a Variety of Angles - White

Why I reached for this accessory pack

Cable raceway is only as clean as its corners. Straight runs look great; the moment you hit an inside corner, an outside return, or need to branch off to a device, the illusion falls apart unless you have the right fittings. That’s exactly where D-Line’s medium accessory pack earns its keep. I used it alongside D-Line’s 1.18 x 0.59 in (30 x 15 mm) raceway to tidy a small home office and a short TV drop, and the assortment covered every angle I ran into without a trip back to the store.

What’s in the pack (and why it matters)

The pack includes:
- 1 flat bend
- 2 internal bends
- 2 external bends
- 1 tee
- 2 straight connectors
- 2 end caps

In real use, that’s a sensible spread. The two internal and two external bends handle most baseboard and wall corners, the tee is handy for splitting to a printer or soundbar, and the straight connectors save you when a run is a touch longer than a single length. End caps finish wall penetrations or cable terminations with a proper stop.

I especially appreciated that the bends and tee are clip-over parts with rear grip tabs. You can mount your straight raceway first, get your lids on, then snap the fittings over the top. No wrestling with hidden clips or screws, and no disturbing adhesive you’ve just set. The connectors and end caps have internal shoulders that tuck under the raceway lid so the joints sit flush. That small detail makes seams look intentional, not like an afterthought.

Installation experience

My workflow looked like this:
1. Sketch the route, mark wall centers and corner transitions with light pencil lines, and measure twice.
2. Cut straight lengths with a miter box and fine-tooth hacksaw (a PVC pipe cutter also works for quick, clean cuts).
3. Dry-fit everything, including the accessories, to confirm alignment and cable capacity around corners.
4. Prep surfaces with isopropyl alcohol and a lint-free cloth for the self-adhesive on the straight lengths.
5. Commit the straight runs to the wall, then clip the bends and tee in place.
6. Pop on end caps and connectors, check for lid engagement, and run a fingertip along seams to seat them fully.

Two practical tips:
- The adhesive on the D-Line straight lengths is strong and essentially a one-shot affair. I like to peel a few inches of backing at a time from each end, align to my pencil line, and work toward the middle. If you have to match a long run, use a level as a guide while you press down.
- Let the accessory pieces “forgive” your cuts. If you undershoot by a millimeter, the clip-over bends neatly span the gap. If you overshoot, trim again rather than forcing a buckle that will show.

All the fittings snapped on with reassuring resistance. I didn’t need tools, though on one tight outside corner I used a plastic trim tool to nudge the edges home. Once engaged, nothing felt loose or rattly.

Fit, finish, and appearance

Out of the box, the color match to the white D-Line raceway was spot-on—no chalky or glossy mismatch. Mold quality is high for this category; minimal flashing, consistent wall thickness, and clean edges. Once clipped on, seams are visible if you’re looking for them, but the internal shoulders and overlapping geometry make everything appear cohesive. On a white baseboard, the whole run read as a single profile rather than a chain of parts.

If you plan to paint, the plastic takes it well. I gave the fittings a light scuff with 320-grit and wiped them down, then used an adhesion-promoting primer and acrylic latex topcoat. The finish leveled nicely without telegraphing the joint lines any more than the straight sections.

Capacity and routing realities

The medium size (1.18 x 0.59 in internal profile) is best suited for two typical low-voltage cables or a slim AC cord plus one data cable. I comfortably ran:
- A TV power cord and an HDMI, or
- Two speaker wires, or
- One Cat6 and one coax

Corners reduce effective capacity a bit. If your bundle is already snug on the straight, expect a tighter fit in bends. I wouldn’t try to stuff multiple thick, braided power cords through a 90-degree corner in this size; step up to a larger raceway if that’s your scenario. For signal integrity, maintain gentle radii on coax and Category cable where possible—these fittings keep bends neat but they do set a fixed radius.

A note on separation: don’t mix mains and low-voltage in the same raceway unless your local code and the raceway’s ratings allow it. The pack doesn’t change that rule; treat it as an aesthetic and routing aid, not a code workaround.

Durability and day-to-day use

After snapping everything in, I tugged at each fitting and ran cables in and out a few times to scope any weak links. The clip tabs held firm, and lids stayed latched. Over several weeks, nothing drifted or gapped, and accidental brushes with a vacuum and chair leg didn’t dislodge the corners. That’s partly the straight lengths’ adhesive doing its job, but the fittings contribute by maintaining even pressure and alignment at the joints.

Where it could be better

• Pack composition: One tee is enough for many setups, but if you’re distributing to multiple devices around a desk, a second tee would be welcome. Likewise, I’d trade one internal bend for another flat bend in some rooms with long baseboard jogs.
• Size specificity: These only fit D-Line’s medium (30 x 15 mm) profile. That’s by design, but it means you can’t mix sizes within the same run, and they won’t cross-fit other brands.
• Corner capacity: The molded radius is tidy but not generous. If you’re dealing with thicker appliance cords, you’ll feel the squeeze at 90s. Plan your cable mix or go up a size before you cut.

Tips for a cleaner finish

• Cut lids and bases together for consistent lengths and tighter seams.
• Face the lid opening upward on baseboards if you expect to add or swap a cable later; downward if you want the seam fully out of sight.
• Use the connectors even for seemingly perfect butt joints; they maintain alignment over time.
• Pre-label cables before you close everything up. It saves future rework.

Who it’s for

• Home offices and TV areas with one to three cables that need to turn corners or branch discretely.
• Renters and homeowners who want a neat, paintable solution without mudding or opening walls.
• DIYers who value fittings that tolerate minor cut errors and still finish flush.

If you’re wiring a studio full of gear or routing thick, inflexible cables, consider the larger D-Line profile and the corresponding accessory set instead.

Recommendation

I recommend the D-Line medium accessory pack. It rounds out the raceway system with well-designed, color-matched fittings that snap on securely, hide small cutting imperfections, and produce a polished, contiguous look around corners and junctions. The clip-over design speeds installation and keeps stress off the adhesive while you work. Capacity at corners is the only real constraint, and that’s intrinsic to the medium profile rather than a flaw in the fittings. If your cable bundle fits this size, these accessories will make your run look intentional and stay put.
