B-LINE BLCD12BL – Frequently Asked Questions
1) How many low voltage cables can a 4 inch B-Line BLCD12BL J-hook hold?
The BLCD12BL is a 4 inch ring, and Eaton B-Line rates the fill at 40 percent maximum based on TIA 569-B. So you size the bundle to fill no more than 40 percent of that 4 inch ring opening rather than packing it full. Load capacity on the support is 20 lb.
2) Can I run power cable through these blue B-Line cable support rings?
No. The BLCD12BL is a datacomm and low voltage support fastener, meant for structured cabling, coax, and similar low voltage runs. Line voltage branch circuit wiring belongs in its own raceway or on supports rated for it. The blue color is a common way installers keep the low voltage pathway visually separate from other trades overhead.
3) What is the weight rating on the BLCD12BL cable support ring?
20 lb per support. With hangers on five foot centers, that is 20 lb of cable bundle carried at each point, which is what governs how many cables you can hang before the ring, not the fill percentage, becomes the limit.
4) What size opening does the B-Line BLCD12BL ring actually give me overhead?
The ring measures 4 inches in diameter with a 2.5 inch height. That is the clearance you need to plan for above ceiling grid or below deck when you lay out the pathway, and it is the dimension to check against an existing tray or conduit run you are threading past.
5) Should I use J-hook style cable rings or cable tray for a low voltage riser?
Rings like the BLCD12BL are the lighter-duty answer: a dangle cable support hung on five foot centers, 20 lb per point, good for branch runs and drops in a ceiling. Cable tray is the choice for a backbone carrying heavy bundle counts continuously, where you need the cable fully supported along its length rather than at intervals. Contractors commonly use tray on the main pathway and rings to break out to work areas.
6) What part number do I order for the blue 4 inch Eaton B-Line dangle cable support?
Order model BLCD12BL. That is the blue, 4 inch ring version of the Eaton B-Line datacomm support fastener, rated 20 lb.
