50' x 3/8" coil. Another Innovation manufactured by MoreBeer!. When compared with 5/16" coils that are usually used to make draft boxes, the 3/8" coil holds more beer, cools faster, yet because the resistance is less the beer can be pushed through the lines with less CO2 pressure. Less applied CO2 pressure means the beer does not overcarbonate and foam wildly if a keg is left on tap for longer than an afternoon. Overcarbonation can be an issue for homebrewers or beer drinkers who are using a draft box for an overnight party or weekend. 8 1/2" wide x 10" tall. 304 grade stainless steel
