Bought this 55" floating shelf to pair with my new Samsung 75"4K TV. It conceals the extra cables nicely behind the center cabinet. My goal was to conceal the unused Cat5, Coaxial, and HDMI cables so I can easily connect them if necessary without moving the TV off the wall.
Assembly took an hour or so by myself. I recommend you find your wall studs ahead of time and be prepared to drill extra holes in the floating shelf because the pre-drilled mounting holes are unlikely to line up with your wall stud pattern. The kit provides wood and cement screws. I was only able land one screw on each end. So the weight is being held by two studded screws, and I'm okay with that. The kit provides some nice concealing stickers to cover up the exposed fasteners and any extra holes you may have had to drill.
Recommend traditional practice of using a straight edge and proper carpenter's level to make alignment lines and marks prior to drilling any holes.
This shelf has an opening on the left hand side that appears to be intended a wifi router antenna. But you can obviously use this for something else if need be.
I discourage concealing a modem or router within the center cabinet because there is little ventilation other than that through the cable ports. The trapped heat could damage your devices. It fits well with our furniture setup.
It comes flat-pack and you need to assemble it yourself.
I found it was actually easier to mount the back panel on the wall and then assemble the rack in place. This saved me from trying to hold the bulky rack and drill lag screws at the same time.
The keys/locks are a bit 'crunchy', but they work and i dont access it often.
The cable inlets at the top/bottom are knock-outs. The metal tabs that hold them in are pretty sharp. I filed them down to avoid damaging my cables. It fits well with our furniture setup. It fits perfectly in our space.
