Has anyone used the "Chinese finger trap" style support grips for vertical runs of outdoor Cat5 cable in conduit?
I need to support 8 - 10 cables in a 150 ft straight run of 2 inch conduit, there is a pull box with a support hook at the top of this run, then another ~30 feet of conduit to a box at the top where the individual cables would go through glands and out to the radios. I did a test with a grip for 0.85 to 1.00 inch cable diameter, and a cable bundle that measured maybe 0.75 to 0.85 inches, and it's very, very difficult to pass the bundle through the grip. I can't see sliding 50 feet of cable through it. Even just a foot or two was a challenge. Yet I'm reluctant to just use a larger grip, for fear it won't grip properly. Is there a trick to using these things? https://www.graybar.com/store/en/gb/0850-to-1-inch-kellems-galvanized-steel- single-eye-bus-drop-support-grip-88147585
