True tape is a flat tape that doesn't stretch, and is marked with a number every foot or two. It's about 1/4" wide, and 1/32" thick. It usually comes on spools about the same size as a 500' spool of #12 THHN. There's usually about 3000' on a spool.

It can be pulled into a conduit with a fishtape, it pulls easily in steel conduit, but tends to 'glue' itself to PVC. Not so bad if it's cold, but you almost can't get it pulled around 4-90's if it's hot. You can pull it pretty hard, I've rarely if ever broken it by hand. I've never tried blowing or sucking it in with a mouse, I doubt it would work. It can usually be pulled in with a masons line though.

Since it doesn't stretch, and has foot markings on it, it's ideal for measuring a conduit run of any size. Be sure to add a bit for each 90. Also, you must know how to subtract, seems a few guys will mess this up!

Conduit Measuring Tape ...............................(Not actual size or to scale...LMAO)


Blow/suck/pull it in however ...just get it in.
We leave it IN the conduit until we are ready to pull the run for a couple of reasons:
1 - it's cheap
2 - it can be used to drag a heavier line through the pipe if need be
3 - you can check that the run hasn't been broken/jammed BEFORE you start the real pull
4 - etc

Celtic, I've never seen the man pons. We've always used the 'mice'. Little nerf cylinder with eye hooks at either end and sized for the conduit.

Also, most of our long runs are in plenum ceilings which require compression fittings. Never seem to lose much vacuum suction with those.

true tape or conduit measuring tape

what is the best way to get true tape from point to point on a long runs of conduit , does anyone have trouble with it breaking half way ? looking for solutions what about leaving it in the conduit and it will not come out after one day ?:(
we have runs that are 289feet to 300 feet long cant run a fish tape , and after you pull in the true tape we pull it back out to save money on the cost of the tape just and leave a string in the pipe to pull in the 1/4 rope to pull in the larger rope but if we leave the true tape in over nite it does not come out the next day it sticks ?just thougth someone had the same problem and could tell us how they do there measuring on long lengths . but i get tried of hours wasted . my company cant buy rolls of true tape it cost 45 dollars a roll we would spend lots as we have hundreds of conduits to measure on one job ?

A vacuum, an air compressor and a sandwich baggie.
we actually use pieces of plastic bags from convenience stores...

Yep. I agree. Do they leave "true tape" in the pipe?
until we use it to pull in the larger rope needed to pull the wire.

yes, yes, yes and etc:laughing:

Get a laser tape.
god damn crack addict salesmen...how in the heck is a laser tape gonna measure through 3 - 90's?

the plastic bag from the convenience store will work on runs with SS fittings (without taping them) for upto about 200' or so...yes, this is from experience...

true tape costs <$0.02/foot...that is $6 for a 300 foot run...how much labor $ are spent pulling the true tape, then pulling it out and pulling in pulling string that costs about $0.01/ft?

talk about tripping of dollars to save nickels...

I have had problems with true tape when it gets wet on long runs. usually blowing the pipe out with a vac for half an hour or so frees it right up.

IMHO...
Saving the true tape IS not saving anyone any money.

You pull it in, you tie something else off to it, you pull it out ~ being careful not to get it all "rat nested", roll it up or re-use it right away.

That is actually a lot of time. The time spent is not worth the cost.
Pull it in - move.

The only time I would consider saving the tape is if it's the kevlar version:


1/4" version ~ Size 3000' (914 m) Capacity 39243 - 1250 lbs

3/8" version~ average breaking strength 39244 - 1800 lbs.

1/2" version ~ average breaking strength 39245 - 2500 lbs.
