Made to Fit standard thin-walled EMT

What's EMT?

EMT is one type of tubing normally used to carry electrical wires. The three types are, from lightest to thickest: Electrical-Mechanical Tubing (EMT), InterMediate-(weight) Tubing (IMT) and Rigid Metal Conduit (RMC). They all have their own standard sizes, which is to say they are not the same as what they're called. A one-inch EMT is actually more than an 1/8th larger than 1" on the outside: it's 1.167"! So....

IMPORTANT: Be sure of the type and diameter you will be attaching to before ordering! Opened packages will not be accepted for return.

EMT is used in picnic and event canopies typically (often due to local regulation) under 8 feet tall, and are great for a wide variety of structures where strength and light weight are both prized. For example, nearly all the photos on this site were taken with my EMT-based technical-photography platform.

HEADS-UP: EMT ≠ Water pipe. If what you're looking at is a copper water pipe, that's not EMT, and the sizes are different. We're working on extensions to the Tubing line to work with copper water pipes like we have in all our houses, but they're not there yet.

In other uses where you might be running cables around existing--live--EMT runs, make sure the tubing is well secured in place, and be very careful to not put excessive weight on the tubing. As long as you're being safe about it, 4CELNK-YR will help you run cables where you need them, and change them when you need that.

What sizes are currently available?

4CELNK-YR clips in the EMT series are specially sized to fit the following EMT tube sizes:

Type & Size Nominal O.D. Wall thickness 4CELNK-YR SKU Availability
EMT 1/2″ (16 mm) 0.706″ (17.9 mm) 0.042″ (1.07 mm) 2018-027-108 Available
EMT 3/4 (21) 0.922″ (23.4) 0.049″ (1.25) 2018-027-109 Available
EMT 1″ (27) 1.163″ (29.5) 0.057″ (1.45) 2018-027-110 Usually in-stock
EMT 1-1/4″ (35) 1.51″ (38.4) 0.065″ (1.65) 2018-027-011 Available
EMT 1-1/2″ (41) 1.74 (44.2) 0.065″ (1.65) Not Assigned Contact us if you’re interested.

Again, be very sure about what size you're getting. Measure it with a caliper if you're unsure. If you haven't worked with it before, 1" conduit looks deceptively like a 1-1/4" tube, and 3/4" looks like an suspiciously under-sized 1". Measure twice, and if that doesn't work, measure again, but write it down this time. 😉

How many EMT clips will I need?

Learn more...

If you're running 1-2 lightweight, say Cat5 cables, you can get away with 4-5 feet between clips. At the maximum capacity of ~8 Ethernet cables, you'll want to put them more like 2-3 feet depending on the situation.

The smaller 0.5 and 0.75 EMT clips are made to hold more like 3-4 cables each, owing to the lower strength of the EMT it's being attached to. With the lower strength and fewer cords, you can estimate 2-3 feet between clips in those sizes as well.

For example, this photo is the EMT 1.0 clip easily holding 9 x CAT5e Ethernet cables. You can figure a pack of 10 clips will get you about 20 feet for that many cables. Even without the bands, they hold pretty well. And, unlike with tie-wraps, you can change wiring with No Tools and No Waste.

You can read more about this topic in the blog post Cables Heavy?.

How much can the EMT clips hold?

6+ Power Cords? Yeah Right...prove it!

The cable areas in the clips for tubing diameters 1.0 inch and above are designed to hold 7-8 typical "SVT" power cords (UL-Type SVT, 3C/18AWG 300V, ~6mm in diameter).

The under-1.0 inch sizes are made to handle 4-5 SVTs.

"Well yeah, but my cables are HEAVY!" The thing to remember is that no component is ever infinitely strong, nor will anything (besides time itself) last forever. The same is true with 4CELNK-YR clips. There is some large amount of force that will break them. I haven't reached it yet, but it's not at all impossible to yank on a cable and pull it out of the clip. (If you're going to be violently pulling the cables, then maybe stick with tie-wraps)

From what I've been able to tell, "a couple pounds" (~1kg) is just fine as far as holding strength. I might be inclined to add more bands (5-6 instead of 3-4) up to about 5 pounds (2.2 kg), but beyond that weight you should consider adding more clips. A typical "good" straight run of 6+ ethernet cables would normally have a clip about every 3-4 feet (~1 meter) or so, more if the cables need more support.

But, beware: if you put only one clip every 8 feet, and expect it to hold 20 pounds, that will very likely end in disaster...and the warranty won't cover it.

Installing 4CELNK-YR Cable Clips

Gently spread the arms and slide clip over tube. Avoid Twisting the clip. (View More...)

Yes, that's all there is. Snap them on, add bands if you think they'll be needed, then and start adding cables. See the section farther down on how to set the tension using the bands, but often they're not needed.

NOTE: When you do this, the clips may make "crackling" noises, and there might be discoloration of the plastic on the inside edge. This is actually normal for this kind of 3D-printed part.

IMPORTANT: Don't spread the arms out too far! The more you bend them, and the more often you bend them, the more they will lose their "spring" over time. Yes, they can actually be spread quite large and they will "work" afterwards. But, never as well as before being over-stressed.

Setting the 4CELNK-YR Holding Tension

Add bands from the included Bag-O-Bands to get the tension just right. (View More...)

The clips should stay in place and adequately hold the cables that you plan to use. 3 is typical, going to 5 or more when the clip is full.

If you need to later change the number of bands, just pull any captured cables out, add the other bands, then put them all back in again. Easy, with Zero Waste!

Some users report not needing to use any bands at all; that will work well for few shaker cables, or just a couple USB cables. Add more bands for larger bunches, or where you want the bundles to stay in place a little better. There should be enough provided so you get about 5 bands per piece in the package.

TIP: The bands that ship with 4CELNK-YR are actually children's 1" hair bands: they're cheap, and available most everywhere. If you want everything really locked down, with a little "security", you could even use...gasp!...a tie wrap.

Adding and Removing Cables

There's instructions?...

Adding Cables

Now comes the easy part!

  1. Grasp the inside arm with one hand.
  2. Push the cable against the outside arm until you can press the cable into the capture area.
  3. Optional: Stand back and ask "whoa...where's the cut tie-wrap?"


Removing Cables

Here's where it gets impossible for tie-wraps...

  1. Separate the cable you want to remove from the others in the bundle.
  2. Grasp the outside arm with one hand.
  3. Push the cable against the inside arm until there's enough room between the arms to pull it out.
  4. Do NOT throw wasted tie-wraps in the garbage...since there are none.

CAUTION: If you pull the cable out too quickly from the capture area, the inside arm might snap back and hit your fingertips.

Warnings & Cautions

View More...

Please keep the following in mind when using 4CELNK-YR cable clips:

Watch for damaged, worn, frayed or otherwise dangerous cables, and replace all that are unsafe.

Dangling, partially-secured cords beneath desks, tables, and in shelving can in some instances present electrocution and strangling hazards. Be wary!

The 4CELNK-YR arms are closely spaced, and there is spring tension holding them together. Use with care to avoid getting pinched or struck by the arms.

4CELNK-YR Cable Clips are not UL-Listed, they are not specially plenum-rated, nor are they flame-retardant.

4CELNK-YR Cable Clips are not a "safety device".

4CELNK-YR Cable Clips are not specially treated for UV-resistance. Using 4CELNK-YR outdoors, or in a high-UV environment can cause them to age more quickly, and, ultimately, fail sooner.

4CELNK-YR Cable Clips, including the Rack Series, have not been NSF-certified for use in commercial kitchens.

4CELNK-YR cable clips are made from ABS plastic: tough, but not unbreakable. Don't overload the clips.

There may be other hazards associated with your doing with cables whatever it is you're doing. Please always be aware of your surroundings, and be careful.
