Quick answer
A Lineloc V is a small, lightweight tensioner that locks thin cord in place, letting you adjust tent guylines quickly without tying knots. It works best with 1–2 mm cord like Zpacks Z-Line.
Why use a Lineloc V over a knot?
Traditional knot adjustments take time and can slip under load. A Lineloc V lets you tug the free end to tighten and release the cord by pinching the V groove—no knot tying required. The trade-off is that the adjuster adds a tiny bit of weight (~0.3 g each) and costs a little more than cord alone. For most backpackers, the speed and reliability are worth it.
What cord works with Lineloc V?
Zpacks Lineloc V parts are custom-made with a tighter V groove to securely hold thin 1–2 mm cord. The matched 1.3 mm Z-Line cord gives a slip-free hold. Thicker cord may not fit or lock properly, and very slippery dyneema cord may require a different tensioner.
Frequently asked questions about Lineloc V
How do I attach a Lineloc V to my tent?
Most tent corners have a small loop. Feed the cord through the loop, then through the large eye of the Lineloc V. Pass the cord around the center post and back through the small V groove. Pull the free end to tighten.
How do I adjust tension in the field?
Pull the free end of the cord away from the tent to tighten. To loosen, pinch the cord at the V groove to release the lock, then slide the adjuster toward the tent stake.
Can I use Lineloc V with old guyline cord?
It works best with 1–2 mm static cord like Zpacks Z-Line. Thicker or stretchy cord may not lock properly. If your cord is thicker than 2 mm, consider a larger tensioner or a knot. Test the grip on your existing cord before relying on it for a trip.
Do I need one per guyline?
Yes. Place one Lineloc V on each adjustable tension line. For a typical tent, you need 4–6 adjusters (one per corner or peak guyout).
