What is a Jumper Box?

A Jumper Box™ is a mobile bar or beer trailer’s new best friend! Inspired by our signature line of premium Jockey Boxes, a Jumper Box™ is essentially a jockey box without faucets and can be integrated into any vehicle or structure from where you need to dispense draft beer. 

HOW IT WORKS 

As beer leaves a keg, it flows into the Jumper Box™ and travels through the coils until it reaches your faucets (“taps”)—wherever they’re mounted—where your beer is dispensed. A Jumper Box™ is the reliable middle man between your beer and beer trailer.

When you fill a Jumper Box™ with ice it surrounds the coils, which chills the beer inside of them down to a proper serving temperature so you get a cold pint, everytime.  

NO REFRIGERATION REQUIRED

Installing a commercial cooler or refrigeration unit inside your trailer to keep your beer cold will be insanely cost-prohibitive, cut into the valuable interior footprint of your working space, and make you so cold that you’d be better off turning it into an ice cream truck.

Do I need to keep the kegs cold? The beauty of Jumper Boxes™ is that they’re designed to allow the ice to do all the work by chilling the beer as it circulates through the coils. While prior refrigeration of your kegs before you arrive at your event or icing the kegs on-site is not necessary, it will help minimize the effects of ambient temperature inside your trailer on extremely hot days.

Rest assured, Jumper Boxes™ will chill your very first (and every subsequent) pour from a keg at room temperature (~ 70° F) down to a proper serving temperature, under 40° F.  

EQUIPMENT NEEDED

If you’re a brewery or an established beer trailer, chances are you probably already have the shortlist of accessories needed to complement the integration of a Jumper Box™ into your mobile bar setup. Otherwise, because the layouts of beer trailers can be so diverse, you have the leeway to choose the additional equipment a la carte or as part of a packaged Shank Kit. 

In either case, here’s what you’ll need to transfer beer from its keg to your Jumper Box™ and from your Jumper Box™ to your guests' glasses.

• CO tank | CO2 is the gas used to move beer from its keg
• CO2 regulator | Regulates the gas pressure, and (optionally) allows a gas manifold to be connected to it
• Gas manifold (optional) | Allows you to dispense CO2 to multiple different kegs (via one or multiple Jumper Boxes™)at the same time
• Gas tubing | Carries CO2 from its tank to a keg
• Coupler | Attaches to your keg, which allows CO2 in and beer out
• Keg jumper tubing | Carries beer from its keg to your Jumper Box™
• Shank jumper tubing (same as keg jumper tubing, but smaller in diameter) | Carries beer from your Jumper Box™ to a faucet shank
• Faucet shank | The bridge between your shank jumper tubing and your faucet
• Faucet | From where your beer is dispensed

If you’re new to the game, we have additional resources to help you become experts in pouring draft beer anywhere. While you’ll find that these how-to guides and instructional videos focus on their popular predecessor, jockey boxes, the philosophies and many of the applications transfer synonymously to Jumper Boxes™.

There is an emerging culture of mobile bars and beer trailers that will be changing the landscape of hospitality at special events. Jumper Boxes™ are the secret sauce to satisfying the demands of thirsty entrepreneurs and their guests by enhancing your bar service while bringing people together in a fun, memorable way.
