Greetings,To use the coil, you need the following:1) Duotight 8mm OD (outer diameter) tubing for going into and out of the coil, and to easily connect to your keg and beer faucet.2) If your "tap lines" end at the typically beer faucet shank, you need a Duotight 8mm push-in fitting with female threads (search the Morebeer website for "Beer Faucet Shank | Stainless | 4" | 8 mm Duotight Adapter | Intertap® | NukaTap" for a good picture of the assembly).3) If you have ball lock kegs, you can use either a Duotight Ball Lock QD Beverage Out Quick Disconnect Push-In Fitting or, if you already have flared (threaded) beverage out connectors, you can use Duotight Push-In Fitting - 8 mm (5/16 in.) x 1/4 in. Flare (search the Morebeer website for SKU: DUO106, click on Duotight Push-In Fitting - 8 mm (5/16 in.) x 1/4 in. Flare, and look for the image of the adapter attached to a beverage out connector).4) If you are making an ice chest beer jockey you can just drill 10 mm holes through the wall of the ice chest (towards the top to be above the ice water line) to get the beer from the keg to the coil. If you want a more elaborate assembly, you can use threaded pass-through shanks with Duotight connects on both ends.Hope that helps.

There are two coils - one inside and one outside. Doing some napkin math, it looks to be closer to the 45ft per coil. The outer coil measures about 9" wide and 11" long. Double that for the 4 sides (two 9" and two 11" = 40"). There are 14 loops on that outer coil (more or less since the first and last bend are partial). That equals to about 46ish feet ((40 X 14) / 12). I will say whatever the length, it's plenty enough to get a warm keg down to serving temp on a hot summer day.
