Questions and Answers

ANSWER: You must first understand, acording to EIA/TIA 568 Standards, the data cable bend radius must never be less than 4 times the cable diameter or 1" for a 1/4" diameter cable. This standard is established so designed communication bandwidth be maintained over the entire length of the data cable. This must be adhered to during insallation as it is much more costly to repair it later. Cable Joe therefore is the best solution available for pulling cables around corners and over long distances rapidly and with no stretching or pinching damage to the cables.

It is common for a certified installation to have a person at a corner guiding the data cables around a corner. Using a hand-over-hand method he pulls the cable so it will not snag on a corner or obstacle. Cable Joe is the perfect tool to save time and money by preventing cable damage with more effective use of installation personnel. Simply mount onto any surface -- joists, trays, or lag bolt to walls. The "clamp-on" feature is simple yet effective. Cable Joe can be clamped to a cable tray, bench or handy rail, or may be positioned at the rear of an installer's vehicle. In this way Cable Joe acts as an "extra-hand" when rigging on location.

A typical installation will have a number of cable supply spools (up to 20) at one location, say on a pallet. The installer pulls individual cables from the multiple spools and must guide them to the destination. Cable Joe acts as a convenient funnel for guiding the cables. The installer just fastens the universal clamp to any convenient structure (Pipes, Joists, Studs - or lag bolts in to wood beams) above the pallet. He opens the frame, inserts the cable bundle into the pulley system and then closes the frame. He then rapidly pulls cables to its intended location without them getting bound up or damaged, resulting in a more efficient installation. When finished, he just opens the frame and removes the cables. Several Cable Joes are often used on one cable pull. Cable Joe does the work of two or more people!

Consider this - before Cable Joe there was virtually no such thing as a one man data cable installation crew. Say a customer wants to put in a few cable drops. One person would have to be either pulling or feeding the cables. The other person(s) would have to guide the cables around obstacles so the data cable would not get damaged. Cable Joe provides a spare pair of hands for installers and makes a one-man cable pulling possible around corners and objects thus preventing the cable from snagging or pulling things over. The end result is time saved with no installation damage.



Maintain a maximum bend radius of 4x the cable diameter (4-pair cables)
Never exceed a 90 degree bend

Avoid stretching the cable
Don't exceed 25 lbs. of pulling tension

Apply cable ties loosely and at random intervals
Don't over-tighten cable ties


ANSWER: Cable Joe is designed for installing network data cables (Category 5,5e and Category 6), as opposed to electrical cables. Data cables are completely unlike electrical cables as they are much more fragile. Tremendous stress on Cable Joe is not normal as the installer knows that a MAXIMUM 25 pounds (per EIA/TIA 568 Standards) of pulling force can only be applied to CAT5, 5e and 6 cables during installation. Cable Joe is made of heavy duty 12 gauge cold rolled steel and can easily handle these specifiations.

But to answer your question - we believe that if Cable Joe was used for much heavier tech cables, the round rod between the clamp and rollers could bend. But that is not what Cable Joe is designed for nor should be used.


ANSWER: Cable joe is capable of pulls up to 20 network data cables at once - even around 90 degree angles. After that the installer finds it difficult to physically handle more cables at one time.


ANSWER: Yes - twice. But the users fully admitted they used it for a much heavier tech cable and found Cable Joe was too light duty for that application and bent a part of the frame. But that goes back to the intended use for Cable Joe - as a DATA cable installer. If the user complies with the installations standards of never more than a 25 pound pull, Cable Joe will work flawlessly. These failures were two out of over 15,000 shipped.


ANSWER: Our current count is less that 15 out of 15,000 sold and we am very proud of that. Those had defective welds and were repaired and re-sold to the market via a secondary channel.
