LiteOutdoors Guyline & Tensioner Kit - 1.8mm Diameter - 60 or 100 feet - Ultralight Reflective Tent Cord, Lightweight Non-Slip Cord Adjusters. Camping, Hiking, Paracord

Great product !!!Lightweight and easy to use.Size is good to use with diameters below 550 paracord (4mm).Durability has been good with my youngest son (now 10) on his tarp.He has easily figured out how to use these.I used them on a couple of backyard/garden tarps, due to Chicago being WINDY, and the guylines needing to be adjusted often.You can use a slippery half hitch (type of hitch, not a knot) or a double slippery half hitch, to ensure that it doesn't come loose from the winds.

These really impressed me! They seem to hold extremely well even with tiny 1.18mm microline! I’m using for guying a ham radio antenna mast but these have a million applications. Perfect for ultralight backpacking when paired with some 100lb microcord!

I've tested these with several cord sizes from 1.18 to 2.0mm in Diameter and they hold really well!. Tested holding a tent fly down in 20MPH winds and saw little to no slip. They are simple and effective and the only small diameter cord tensioner I've found that actually works well!

These tensioners are very easy to use and lightweight. I was a bit afraid that they wouldn't work with my cordage, but they worked great with the 1.5mm that I use for my tent.The only downside is that they seem to go out of stock pretty quickly, so if you want them and see that they're available you should probably snag them quickly. I had to wait a few weeks for them to come back into stock to get my set. Well worth the wait though, these are 10/10.

Great product to add to your tent!

The center divider that the cord wraps around is very loose and there is nothing to hold it in place except a small ridge in the center of the plastic. I bought them for my tent guy lines and I'm worried one will pop out and get lost. Don't know how well they will do in the wind or rain. Guess I'll have to wait and see to find out.

I use these line locks in conjunction with 2mm dyneema line to build temporary weather shelters when backpacking. The locks are small and quite secure and helps with not having to deal with messy knots. They weight almost nothing and take up almost no room in your pack.

These tensioners are a huge disappointment. The mechanism that tightens the line is flimsy and flops around everywhere. If you don't get it just right the line pulls right out of them. Hard to imagine trusting them to hold. Feels like they would break very easily.
