I use this ALL the time, thanks so much! Fun story: Had to pull parallel 500s over about 300 feet with a 90 degree turn at the end, used this and it worked so good for the first set, second set however.... We got NEARLY to the end and it got stuck, and our 10,000lb tugger (never went over 1000lbs on the controls) BENT IN HALF. So we rented another one, 6000lbs cuz that's what was available and the rope snapped (7500lb rated rope). So we had to cut through the slab and dig down to our PVC, careful not to damage the water pipes right next to them, cut it open and re-tie the end. It had gotten caught on a cheated pipe from the previous crew who did the groundwork. Pulled through the rest like a charm. Needless to say I had some choice words for the guys that put in that PVC originally lmao
I watched the whole video, and I appreciate the content. Using your knot setup, I just pulled 3 conductor, 4/0 cable through about 70 ft of conduit with 4 full turns. It worked like a charm.
I need to pull a security wire by string through a conduit to my building. I wasn't sure how to attach the string to the wire. I watched some videos and was still a bit confused until I watched yours. Using the big pole to represent the wire and the rope to represent the string made it easy to see and your explanation made it very understandable. Thanks.
The way I was shown when I started in the trade was using a simple overhand knot on the first one then taping the knot and the tail of the string to the wire or cable. It doesn’t matter as much what knot is used before the half hitches, as long as it is secured. The one you used is a lark’s head. It has a few other names (Cow hitch, I think).
Just had the worst wire pull I’ve ever experienced. I’m only a second year apprentice. But my journeyman is on year 15. And it was his worst also. Half hitch was the only knot to use. Never seen it used with the first knot you used. But thanks will try it on the next pull!
Come to think of it, besides being useful for pulling wire, that looks like a great way of pulling a straight run of pvc pipe through a straight run of secondary containment pipe.
I did this on my job, while the boss wasn't looking . Because if he saw me doing it, he'd demand I just use the fish tape in an overfilled pipe. And struggle and stress like the rest of the crew
But how do you pull it? I've got four 2/0 conductors to pull through 130' of pvc.. its ran, but they left 30' on both ends, id like to reclaim some of that, since it's a usable length.
In my 50 years as a sparky never tied knots on wire. Produces too much bulge. Have 7 different sizes of pulling grips. Would weave a grip just the right size for pulling 3#2'S and a #6 ground to one end of a 1/2" nylon pulling rope and weave a larger grip on other end to take care of pulling cable thru 2" conduit. Used both ends of these grips hundred of times over the years and gave it to a young electrician when I retired.
Pulling grips are great also but I was told yesterday( which is why I looked up this knot for home use) that you can use this type of know for fiber jumpers to pull indoor fiberotic cables. If you do damage the fiber you can clean the end and light test it and move on!!! Thanks!
I tend to have the most luck splitting the conductors (usually about 1½' for something like 600 kcmil or something) and folding them through a single smaller knot then tape it with 2" super33 or 88
NOPE NOT that Knot!! Use the Clove hitch. with a couple of half hitches. Works everytime. As well on your clove hitch have the end long enough to tape to that which is being pulled. Keeps the end from loosening up .
Should let people know that this doesn't work well with the synthetic bailing twine type of pull they sell to homeowners at places like home depot. Electrician tape works well, but the twine pull slipped off using this knot. Lots of time wasted.
???? This looks like a good knot for dragging downed tree logs through the forest.... but for *cable pulling??!?* This knot, while it might be secure, is adding *bulk* to the diameter of the cable you're pulling - which is the last thing you'd wanna do. If you make your wire loop well enough, which knot you use will be less important.
