A flush mount plug panel recesses your trailer plug — a 7-pin or 12-pin Narva flat plug — and your 50A Anderson plugs into a single plate that sits into the face of your canopy, drawbar or trailer, instead of dangling off the back on a loop of cable. One clean face, every 12V connection behind it, nothing hanging.
If you've got a Narva plug swinging on its cable and an Anderson connector cable-tied to a rail, this is the fix. Here's what a flush mount panel does, which configuration you need, and how to fit one.
What is a flush mount plug panel?
It's a mounting plate with the connector cut-outs built in. The connector body recesses into the plate so the face sits flush with your panel — the cable enters from behind, so the strain is taken by the panel, not the plug's terminals. Add Anderson cut-outs alongside the trailer plug and your whole 12V side lives behind one plate: trailer lighting, solar input, DC-DC charging and accessory circuits, all in one spot.
Walk through any campground and you'll see the alternative on half the rigs: a Narva plug hanging off the back of a canopy on a loop of cable, an Anderson connector cable-tied to a rail, a surface-mount bracket screwed on at an angle and gone chalky in the sun. It works — right up until it doesn't.
The problem with dangling plugs
Trailer plugs and Anderson connectors were made to be plugged in and unplugged, not to live outdoors unsupported for the life of the vehicle. Let one dangle and three things happen:
The cable takes the load. Every corrugation and every gate you swing, the weight of the connector pulls on the terminals. Pins loosen, contacts arc, and you get intermittent trailer lights you'll chase for a weekend before you find the fault.
Water and dust get in. A hanging plug points every direction except down. On the coast that's corrosion; out west it's bulldust packed so hard you can't seat the plug.
It catches on things. Scrub, gear, your own legs — a connector proud of the panel is a snag point, and eventually something rips it off.
Surface-mount brackets stop the dangling but trade one problem for another: they stand proud, they're usually brittle plastic, and the connector's still exposed.
What a flush mount panel actually does
The connector recesses into the cut-out, the face sits level with the panel, nothing hangs and nothing protrudes. The strain's on the panel, not the terminals. It's not complicated — it's just done properly.

7-pin or 12-pin? Which trailer plug do you need
Start with your plug, then count your charge circuits.
7-pin flat is standard trailer lighting — tail, brake, indicators, earth. If your trailer or camper runs lights and nothing else, that's your plug.
12-pin flat adds five circuits on top of the 7-pin layout: electric brakes, reversing lights, and a high-amp 12V feed for battery charging, fridges and auxiliary gear. Most modern caravans and any camper with a battery system run 12-pin.
Not sure? Look at the plug already on your rig and count the pins.
How many Anderson plug slots?
Match the Anderson cut-outs to your charging setup — the panels take standard 50A Anderson SB50 connectors:
| Your setup | Configuration |
|---|---|
| Trailer lighting only, no battery system | Panel only |
| Portable solar blanket, or a single charge line | + 1 Anderson slot |
| DC-DC charger plus solar input | + 2 Anderson slots |
Need three slots or a layout that isn't listed? These are made to order, so a custom configuration is a conversation, not a six-week special order.
You can upgrade later without re-cutting
On the 7-pin range, the 1-slot and 2-slot panels share the same plate footprint. Cut your canopy once for the 1-slot, and if you add a DC-DC charger or a second solar input down the track, the 2-slot drops straight into the opening you already have. No re-cutting a finished canopy, no filling and re-sealing — swap the plate, run the extra cable, done.
Not all panels are the same
The bargain-bin printed parts are usually run in whatever filament was cheapest — material that softens around 60°C, and the inside of a black canopy through a Queensland summer gets well past that. The part sags, the cut-out distorts, and your plug no longer seats. The other common option handles heat but chalks and cracks under twelve months of UV, usually right at the mounting holes.
Vankor panels are run in a UV-stable engineering-grade filament chosen for permanent outdoor mounting — it doesn't go brittle, handles heat, and flexes enough to absorb a knock rather than shatter. Paired with stainless hardware, so you don't get rust streaks down your alloy.
How to fit a flush mount plug panel (and mount your Anderson plug)
Straightforward job, about twenty minutes.
- Pick your spot. Somewhere accessible with clearance behind for the cable. Rear canopy face and caravan drawbar are the two most common.
- Mark and cut. Use the panel as your template. Mark the cut-out and the fixing holes, then cut with a jigsaw or hole saw depending on the material. Deburr the edges.
- Test fit. Panel in, plug seated, before you commit.
- Seal and fix. Run a bead of automotive sealant around the back of the panel flange, then bolt it down with the stainless hardware. On aluminium canopies, use a nylon washer or a smear of lanolin between the stainless and the alloy to stop galvanic corrosion.
- Wire and seat. Terminate your plug and Anderson connectors, seat them in the cut-outs, done.
Supplying canopy builders
We also supply these to an Australian ute canopy builder who fits them as standard. A dangling plug on a $12,000 canopy is the detail a customer notices. For a builder the value's simple: same panel, same cut-out, same install every time; configuration to spec; made here, made to order, no container lead times or minimum runs; and custom geometry when a build needs it. If you're building canopies, trays, campers or trailers, get in touch about trade pricing.
Common questions
What is a flush mount plug panel?
A plate with the connector cut-outs built in, so your trailer plug and Anderson plugs recess into the face of your canopy, drawbar or trailer instead of hanging off a cable. The cable enters from behind, so the strain sits on the panel, not the terminals.
How do I mount an Anderson plug in a canopy?
Cut the panel's Anderson opening into the canopy face, seal the flange, bolt the panel down with stainless hardware, then wire and seat your 50A Anderson SB50 connector into the recess. Full steps above.
7-pin or 12-pin — which do I need?
7-pin runs trailer lighting only. 12-pin adds electric brakes, reversing lights and a high-amp charge feed. Most caravans and battery-equipped campers run 12-pin. Count the pins on your existing plug.
Does the panel include the Narva plug or Anderson connectors?
No — panel and stainless hardware only. The Anderson slots are sized for standard 50A SB50 connectors. Most people already have a plug, or want to choose their own, and buying them separately usually works out cheaper.
Will it fit my canopy?
It fits any flat panel you can cut — aluminium, fibreglass, steel or composite. Check you've got clearance behind the mounting point for the cable run.
What about water and dust?
Seated with sealant behind the flange, water and bulldust run off the face rather than pooling in the connector — far better than a hanging plug that points wherever gravity leaves it.
