Watch out for those innerduct pulling eyes – they’ve got sharp teeth!
We were making a short video for the various duct pulling tools last week: wire mesh grips, innerduct pulling eyes, the expanding shell pullers and the sealed “bullet” pullers. I was installing them onto typical pieces of duct to compare the time and methods involved.
 

Getting a Wire Mesh Grip onto a 1-1/4″ duct took some exertion, and then I picked up a 00604-series Innerduct Pulling Eye and threaded that on. (The tapered threads lead to the “carrot” nickname.) Cranked it on tight in a few seconds, but didn’t notice the sharp teeth imprinting themselves into my palm.
Picked up a 00620 Expanding Shell Puller next; slotted that in and cranked the eye tight to engage the shells– and noticed a few drops on the eye of the puller as I put it down again. Kept going, though; only one more puller…
I realized that my hand was shredded as I was socketing the 00650 Sealed Duct Puller over the end of the duct. The o-ring in the outer sleeve sealed down over the end of the duct and the eye was already smeared red. Turned the eye until the shells engaged the inside wall and gave it a tug to show that it had bit into the duct.
And there it is: four options from DCD Design. Each one has advantages, and one of them is particularly sharp! You can see about three bandages on my hand in this second take, and I make sure to mention gloves as an option.
