Frequently Asked Questions
Q: How many cables can be pulled through it?
A: For cables the size of a CATEGORY 5e, up to around 25 at a time works fine, although it’s equally effective with fewer cables, or even a single cable. For larger cables such as 25pr, 4 or 5 at a time works fine.
Q: Can it be left in place permanently after use?
A: Yes, and if it is used in a remote location in a building, it’s fine to leave the cables inside. However, if it’s located in a busy location where you or someone else is likely to pull more cables through it, you may want to consider removing your cables from the pull elbow and dressing them beside it. This keeps them clear of the next set of cables and reduces the chance of damage to your cables when more are pulled through.
Q: How many corners can be pulled around in the same run?
A: In a typical run, 2 or 3 work fine. It helps if you have a helper pulling the cables off the reels or out of the boxes, so that drag is not added to the pull tension.
TIP: To make the cables glide through the Pull Elbow even easier, I take a short length of a candle (just a 1½ “- 2” piece of a common household wax candle) and slide it back and forth along the inside of the Pull Elbow, to “wax” the surface that the cables slide over. Just press the wax against the inner surface of the tube. This takes about a minute to do, and lasts for at least a few months. Ask any skier if they would ski on un-waxed skis.

Q: What is involved with mounting it?
A: The most important thing is to mount it solidly!
For mounting to building steel, just use a couple of ¼-20 screws ½” long, (1/4” screws or bolts, 20 threads per inch, available at every hardware store or home center) to fasten beam clamps (available at hardware, electrical supply, plumbing supply stores and most home centers) to the Pull Elbow, (see photos) then slide the beam clamps over the metal surface, and TIGHTEN THE BEAM CLAMPS SECURELY! Lay the cables into the pull elbow, put cable ties on the ends to keep them inside, and pull away.

For mounting with wood screws, a cordless drill, #3 phillips bit, and some #12 x 1¼” wood or sheetmetal screws works fine.

For mounting with cable ties, use large strong heavy duty cable ties to fasten it in place, and don’t be afraid to double them up (or triple, at least near the corner where the strain is the greatest)
