Northern Brewer Kegerator King Two Ball Lock Keg Mini Fridge Conversion Kit with Tower Review (2026)
Updated September 21, 2026 · Research-based review
Our verdict
This Northern Brewer kit suits homebrewers converting a mini fridge to serve two kegs through a top-mounted tower. Keeping the fridge door intact is the main strength, and the trade-off is needing a mini fridge roomy enough for two Corny kegs plus tower drilling near the cooling lines.

Trade-offs
- - Mini fridge must be large enough to fit two Corny kegs
- - Top drilling can hit cooling lines on some fridge models
What is included
The Kegerator King kit is built around two Ball Lock Corny-style kegs, a dual faucet draft tower with beer lines and Ball Lock fittings already run to each faucet, and a CO2PO double body CO2 regulator that can control gas pressure to two kegs independently from a single tank. It also includes two Ball Lock gas connector kits, a 5 pound CO2 tank, a countertop drip tray to catch overflow under the tower, and a faucet wrench for servicing the faucets. The kit is sold as everything needed for the conversion except the mini fridge itself, which the buyer supplies.
Top-mounted tower design
Rather than mounting faucets through the fridge door the way a shank-based kit does, this kit uses a tower that sits on top of the fridge, with lines running down into the cabinet to the kegs inside. That approach means the fridge door itself does not need to be drilled or otherwise modified, which matters on a mini fridge where the door often has limited flat space and drilling it could interfere with the door seal or hinge. The trade-off is that the top of the fridge does need to be drilled to route the beer and gas lines down to the kegs, so that surface needs to be a fit for the tower base.
Two-keg capacity
Running two kegs from one mini fridge means the interior needs to be large enough to fit two Corny kegs side by side along with the CO2 tank, which is a tighter fit than many people expect from a compact mini fridge. Anyone planning this build should measure their fridge's usable interior height and width against standard 5 gallon Corny keg dimensions before buying, since not every mini fridge marketed for kegerator conversions actually has room for two kegs plus a tank once shelving is removed. The payoff for the tighter fit is being able to serve two different homebrews at once from a single small fridge.
Installation considerations
Because the tower mounts through the top of the fridge, drilling in the wrong spot risks hitting the refrigerant cooling lines that run through the cabinet on many compact fridge and freezer units, which can ruin the appliance's cooling ability if punctured. Northern Brewer provides instructions to guide the mini fridge conversion process, and following them closely for hole placement matters more with a top-mount tower than with a door-mounted shank kit, where the door cavity is usually more predictable. Anyone unfamiliar with their fridge's internal layout should research or contact the fridge manufacturer before drilling.
Who should buy it
This kit fits homebrewers who specifically want two taps from one mini fridge and prefer keeping the door free of hardware, whether for looks or because the door does not have room for a shank. It is a heavier commitment than a single-faucet kit both in fridge size needed and in drilling risk, so it suits someone comfortable following an installation guide carefully rather than a first-time builder looking for the simplest possible conversion. Compared with Kegco's competing two-tap kits in the same guide, this Northern Brewer kit's main distinction is the top tower layout instead of a door-mounted faucet pair, which is worth weighing against how much usable top surface a given mini fridge actually has.
Frequently asked questions
How many kegs does this kit serve?
It is built for two Ball Lock Corny kegs served through a dual faucet tower from a single CO2 tank via a double body regulator.
Does it require drilling the fridge door?
No, the tower mounts on top of the fridge rather than through the door, but the top does need to be drilled to run the lines down to the kegs.
What size mini fridge do I need?
The interior needs enough room for two 5 gallon Corny kegs plus the CO2 tank, so measure usable height and width before buying rather than assuming a compact fridge will fit both.
Can drilling damage the fridge?
Yes, drilling through the top can hit refrigerant cooling lines on some compact fridge models, so hole placement should follow the included instructions closely.
