Greenlee - Piston, Boxed-1", Fishing (610)

Works excellent for sucking a string through long sections of conduit for pulling a fish tape through it. I was able to hook my shop vaccum to one end of the conduit and suck the piston through it tied to string from the opposite end. Was much easier than I could do it with the string tied to a plastic bag. I have used plastic bags for doing this on shorter distances before but they couldn't get the job done on this pull. I was worried about it being able to get around the angle joints but it travels like a jet. Make sure you have something on the end of your vacuum nozzle, if your nozzle has a larger diameter, because you will be fishing it and a lot of string out of your vacuum if you don't! It's pricey but it's necessary.

I had about a 150’ run of 1” conduit with multiple bends. I tried plastic bags and a piston shape that I made myself but kept coming up about 10’ – 30’ short depending on the direction I tried to pull from. I kept hitting a snag. This piston went through without any problems on the first try.

Works great for shooting string down 120’ long 1” Grey PVC conduit with 2 - 90° and 1 - 45° elbows. Made pulling my #10 wires effortlessly with a little wire lube. Highly recommend this product.

Worked perfectly! Worth the money

I usually just use a wadded piece of plastic - but I had a pull that I was worried about - so stepped up to this - kind of expensive for just a piece of foam - but got the job done - beats the alternative - not getting the job done !

Good price and worked perfect, real time saver

Worked fine. Had a bit of a holdup on corners but 1” conduit corners don’t have a big radius. Used it to pull 4 different pull strings. Would buy again. I tied it like a fishing lure. That seemed to work well.

Just what I wanted!
