4CELNK-YR Rack 0.25 Large Capacity 8-pc Pack (2018-027-123)

These racks, commonly known as stainless-rack shelving, wire-racks, or through their commercial-kitchen association, NSF-racks, consist of 1.0" diameter stainless or chromed-steel vertical posts, with grooves spaced 1-inch apart. Wire shelves and other accessories at held in place via thin plastic wedges that fit around the posts.

4CELNK-YR Rack series is designed to let you have organized cables, tubes and other things for the things you run on the racks, with No Tools, and No Waste.

4CELNK-YR Rack series comes in a One-Tier / Planning Kit, with enough parts for about one tier of a typical 2x4 foot shelving system. Since that Kit includes the three different part types, you can use that to plan your entire installation. Once you've got the planning out of the way, you can get the other clips in convenient 8-piece packs, in the 1.0 tubing, 0.25 wire, and 0.25 large capacity wire clips.

All 4CELNK-YR parts are available in black, red or white. While some will choose based on personal preference, those with truly large installations might want to segment their cabling according to clip color. No matter how you choose to go, 4CELNK-YR give the flexibility to change your installation whenever you want, No Tools, No Waste.

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

The area available on the 0.25 clips, that fit over the shelf racks, is about 6-7 SVT cords, while the 0.25 Large Capacity clips can easily hold 10-12 SVT cords. The Large Capacity clips are more intended for tubes you might find in a hydroponic or laboratory setup.

"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)

If after all that you still need more capacity, consider adding more than one clip, and arranging them around the tube circumference to provide multiple wiring "channels, as in the photo at right."

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.
