Solid, paintable, and attractive - just be cautious as some edges can be sharp
Most of the time I prefer to install everything inside the walls, but sometimes it just isn't worth the trouble. I wanted to run power to my TV, which is wall mounted, but the closest outlet was a couple feet to the side. Running the power horizontally through the wall would have required cutting out a chunk of drywall to drill through the studs. With the Wiremold / Legrand metal raceway, I was able to take the existing outlet box, mount a starter box over it, run raceway a couple feet over the wall, and then use another starter box to bring power back into the wall. At that point running a new outlet higher on the wall in the same stud space is relatively straightforward without having to make unnecessary drywall cuts.The Wiremold / Legrand system works well. The metal raceway has a more substantial feel to it than the plastic parts and is still paintable. Be a bit careful though - some of the edges of parts like the mounting plate can be a bit sharp. I walked away from this project with a few nicks. Also, the way the raceway connects to the boxes can require a bit of work to connect. I had to tweak the little tabs a bit with pliers to get them to slide in easier. I definitely wouldn't hesitate to use this again for a similar project.One other minor note: no fault of Wiremold / Legrand, but my raceway box was delivered bent like a boomerang. I ended up returning that to Amazon and just buying a replacement at the local hardware store. Props to FedEx for leaving it that way on the porch - my wife and I both had a good laugh.

Oldie but goodie.
These Wiremold steel boxes are an old standard. I'm glad you can still buy them. Works great.

Extra room for wiring.
It is deeper so it makes it easier to wire.

Easy to work with
It all goes together pretty easy. If you can use a screwdriver use a screw gun and install screws to the wall with shields. You’re doing fine I just used metal snippers and bent the metal and it went all on really easy.

Good item that's easy to install
I used this in combination with the surface switch and it installed easily and looks great. I cut it with a cut-off wheel and used a file to remove the burrs: a simple task and easy installation.

Just what I wanted
Used to mount ceiling light , works perfect but the screws are a little smaller than the holes that’s on item so I end up using different ones
