Cmple - 2 Port Decorator Wall Plate Insert, 1-Gang Keystone Wall Plate, Standard Keystone Jack Single Gang Wall Plate - White

A simple, flexible way to clean up A/V and data drops

I installed the Cmple two-port keystone insert in a living room media wall and a small home office, using it to bring one Cat 6 run and one HDMI coupler to a neat, single-gang opening. It’s a straightforward part, but it hits the notes that matter: standard keystone sizing, reliable snap-in retention, and compatibility with the decorator-style wall plates most of us already have (including screwless frames). If you want a tidy patch location without committing to a large multi-gang plate, this insert gets you there with minimal fuss.

What it is (and isn’t)

This is a two-port “decorator” keystone insert, sometimes called a Decora strap. You snap in your keystone modules—Ethernet, HDMI, coax, banana plugs, and similar—and then mount the insert into a single-gang box or low-voltage bracket. Finally, you add a standard decorator wall plate over it. The box contains the insert and mounting screws; you’ll need to supply your own keystone jacks and the outer decorator wall plate/cover.

That modularity is the key advantage. It lets you align the aesthetic of your covers (standard or screwless) with the rest of the home, while mixing and matching keystone types as your setup evolves.

Build and design

• Material: ABS plastic with a slight flex that helps during install and reduces the risk of cracking if you over-torque a bit during alignment.
• Keystone retention: The tabs hold standard-sized keystones securely without requiring excess force. I tested with Cat 6, RG6 coax, an HDMI coupler, and banana plug modules; all clicked in cleanly and stayed put.
• Finish: Bright white with a light sheen—neutral and modern, but not a matte finish. The shade is “contractor white,” which may not perfectly match every brand’s “white” cover.
• Edges and mold lines: On one of my units, there was minor plastic flashing along an inside edge. It didn’t affect fit and trimmed away with a utility knife in seconds. Not a dealbreaker, but worth checking before you button up.

Compatibility and fit

This insert lines up with standard decorator frames, including screwless covers from big brands. In my installs, it sat square and true in both a metal single-gang box and a low-voltage old-work bracket. Keystone fit was snug across brands. Two practical notes from use:

• Depth and clearance: If you’re running a bulky HDMI coupler or a stiff coax keystone, a shallow box can feel tight. A deeper box or low-voltage bracket gives you more breathing room and makes dressing the cables easier.
• Recess alignment: Depending on your box, the insert can sit a hair recessed relative to the frame, which some notice with screwless covers. If that bugs you, a small spacer or washer behind the mounting ears evens it out.

Installation experience

Install is about as simple as it gets:

1) Mount the box or old-work bracket.
2) Snap keystones into the insert (I prefer snapping after the insert is loosely mounted to avoid driving against the wall).
3) Secure the insert with the included screws.
4) Attach the decorator wall plate or screwless cover.

The included screws grabbed cleanly and didn’t strip. The holes are consistent with standard electrical boxes and low-voltage brackets. The insert has just enough flex to fine-tune alignment without whitening or stress marks in the plastic.

A couple of small tips:

• Don’t over-tighten. Snug is enough; overtightening can pull the insert slightly off-plane.
• Label your keystones before snapping them in. It’s easier than guessing after the cover goes on.
• If you’re mixing brands (say, a Leviton keystone in this Cmple insert with a Lutron cover), do a quick test fit on a bench. Standardization is good, but tolerances vary—better to know before you’re up on a ladder.

Day-to-day use

Once installed, the insert has been invisible—which is the point. Keystones stay latched, the openings don’t deform with plug/unplug cycles, and the overall look is tidy. I like the two-port configuration for media rooms: it’s enough for a network line plus one A/V feed without tempting you to cram too much into a single gang. In the office, I paired a Cat 6 and an F-type coax keystone, and the cable dressing behind the wall stayed manageable.

If you’re building a larger patch point, you might prefer a multi-gang decorator frame or a dedicated multi-port plate. But for targeted drops, this two-port approach hits a sweet spot between capacity and simplicity.

Where it falls short

No product this inexpensive checks every box, and there are a few quirks:

• Color matching: The white is on the brighter side. If your home uses a specific shade (e.g., “snow” vs “white” between brands), you might notice a slight mismatch next to your covers. With screwless plates, the effect is reduced but still visible in some lighting.
• Slight mold flashing: Not universal, but I saw it on one piece. It’s easy to clean up, yet it signals a mid-tier finish.
• Stand-off depth: In certain boxes, the insert sits slightly recessed relative to the face frame. It won’t affect performance, but if you’re picky about planes and shadows, plan a shim.

None of these issues affected function. They’re mostly aesthetic and easily worked around with careful selection of boxes and covers.

How it compares

Compared to full-face keystone wall plates (where the plate and openings are a single piece), this insert lets you use decorator frames to match the rest of the house, which looks more cohesive—especially under screwless covers. Against pricier “premium” inserts, the trade-off is in finish and ultra-precise color matching, not in core function. Keystone retention and fit were as good as any midrange competitor I’ve used.

Best uses

• Media rooms: Pair Ethernet with HDMI or coax for clean device connections.
• Home office: One data drop and one phone/coax line without upgrading to a two-gang.
• Conference rooms: A/V pass-throughs that you can reconfigure later without redoing the plate.
• Small renovations: Because these are inexpensive and available in multi-packs, you can standardize across several rooms and keep spares for future changes.

Practical advice before you buy

• Plan for depth if you’ll use bulky keystones. A deeper box or low-voltage bracket makes life easier.
• Match your decorator cover brand and color to the rest of the space to minimize shade differences.
• Keep a couple of 6-32 spacers or nylon washers on hand in case you need to bring the insert forward a touch.
• If you expect frequent swaps, stick to name-brand keystones; they tend to have cleaner edges and install/remove more predictably in this insert.

Bottom line

The Cmple two-port keystone insert does exactly what a decorator strap should: it holds standard modules securely, sits cleanly under a decorator plate, and keeps your wall drops organized and swappable. The plastic isn’t boutique, and the white may not match every cover perfectly, but those are minor nits in a part that otherwise performs well. After using it in two different scenarios—one A/V heavy, one data-centric—I’d happily standardize on it for small, clean installations.

Recommendation: I recommend this insert for anyone building tidy, two-port drops in living spaces or offices who wants the flexibility of keystones with the clean look of a decorator frame. It’s dependable, easy to install, and plays nicely with a wide range of jacks and covers. If perfect color matching and top-tier finishing are your top priorities, you may prefer a premium insert from the same brand as your covers. For most projects, though, this strikes the right balance of function, compatibility, and cost.
