One Way Anchor Vise Grape Trellis Coated Wire Tightening Vice 12.5 Gauge 10 Pack

I read a lot of comments about how difficult these were to install. So I took all the precautions. I got extra anchor vises. I cut each piece of wire long so that, if I needed to, I could snip the wire and pull a short piece through the vise and try again. I very carefully straightened each wire end before inserting it into the vise. All that and the installation went smooth. Every vise I used worked perfectly and on the very first try.These things are great. Attaching and stretching the wire on my new grape arbor was the easiest part of the job. Whoever designed these gadgets should have been awarded a Nobel prize.

I found this product easy to use, I did review other people's tips to help. I had no problem putting a 12 gauge wire through and the spring worked great. I am using these as my grape trellis, very strong and the wire has not slipped at all. I have them anchored into a 4x4 redwood, would buy again if I need more.

These worked really well for a small grape trellis I built for my wife. Once you figure out how they work, they are great. I had to go through three of them before I figured it out, but I only needed 6, so I still have one left over. Here's a few suggestions:First, before you begin shoving the wire through, look inside and see how it works. It's basic: a spring and two metal pieces that pinch the wire. You need to be aware of this because you have to guide the wire through the middle of the metal pieces and through the middle of the spring without catching the spring. If you're off a little the wire will move the spring out of position and then the vice is essentially useless, because once the spring is bent or comes out of the vice, you're not going to get it back into position easily. It's not a very resilient spring so you have to make sure you bypass it carefully. Once you get that, you've 90% of the way there.Another side challenge I noticed was that when I cut the wire, it was quite sharp sticking out of the end of the vice - just the kind of thing you'd slice your hand open two years from now after you had forgotten about it. However, I discovered a solution. Leave at least 6 inches of wire on each side before cutting the wire. Use some strong pliers to pull the wire out from the vice, and then use some wire cutters to cut as close as possible to the opening of the vice. If you do it right, the wire will come out ever so slightly when you pull (because of the spring), and then retract into the vice a bit, so that the sharp wire is not sticking out beyond the end of the vice. Then, use a small hammer to tap on the end of the wire to blunt any sharp pieces that might still be a problem.Overall very happy with the product, and would buy again. However, the learning curve was a bit frustrating, especially since these things are over $3 a piece.

We use these to hold up raspberry bushes and to trellis hardy kiwis in the garden with galvanized steel wire. The one way clutch means if you pull the wire through to tighten the tension, it doesn't slip back. Good price, good quality. We've bought more than once as we keep finding more uses for them.

Used these for running the wires on my Raspberry trellis, and they are the way to go. So much nicer than trying to tie knots or using clamps on the wires.

I had to "burn" one of the vises to figure out how to use. It seems logical but is actually counter-intuitive. After you drill the hole, put them on the far side of your post, feed the wire through the post and then into the narrow end of the vise through to the other side.Once I figured this out, they worked like a charm. These should really come with a drill bit size recommendation and a simple drawing. However, read the rest of the recommendations and you get the info.

This was a snap! I was a little hesitant at first, because some pictures make these 1-way clamps look huge. I picked up 12g wire at a local Tractor Supply Company, and these worked perfectly for our grape trellis. I pre drilled the landscape timbers with a 1/8 inch spade bit, placed one at each end of a run, and tensioned with lineman’s pliers. Too easy, and turned out really nice.

Really great, sturdy, thick metal product. Thank you for being reasonable on prices. :)
