4-Line Bundle FAQ
Is 4-line the most common trunk bundle size?
It's a common starting size for craft bars and smaller taprooms — enough taps for a real rotating lineup without the install complexity of a larger commercial system. If you're planning any near-term expansion, it's worth sizing up rather than adding a second bundle later.
What run length is a 4-line bundle rated for?
Custom lengths are cut to your exact installation, typically supporting runs well over 100 feet when paired with the right glycol power pack. Send us your actual distance from cooler to tower and we'll confirm it's within spec.
