Yeah, Kellems grip(s) hung on a hook in the box. Tower guys will hate them because you have to pull all the cables through. I think there are grips that you wrap around the cables and lace up, I haven’t tried those, they look complex.
I think the people who say you need a pull box with a strain relief every 50 feet are being too conservative. I have hung 165 feet or so in 2” conduit and I think it’s fine. I’m not sure I’d try 300 feet. At that height we should all probably be looking at fiber + power. I don’t see why you’d run BBDGE inside conduit. Actually if the entire run is in conduit you could probably use indoor cable, but we end up going through glands from the box at the top. Does the marshmallow fluff inside the BBDGE stay in place, or does it gradually flow down the cable? It’s hard to fight gravity year after year.

So you can put a box in and the grip will have the weight hanging on the box. Since riser grips are expensive, some people do just get a plain kellems grip and hang the bail on a bolt screwed into the back of the box. ....and go ahead and call me a nut if you want to, but if you stuff the pipe 100% full of cables they'll hang with just friction. I'm aware of a 300' vertical run where the only support was a wad of electrical tape at the top. It was done about 15 years ago, and it's still running error free.

We have to retrofit, that sucks. but you guys using conduit, how are you dealing with cable weight? any primary site we build out now, we pre-run 12 ethernet top to bottom, this gets weighty, especially with BBDGE. How often to you put breakout boxes to secure the cable, and what are you tying it off with? cable grips are expensive.
