Hello, I have a 1/2 inch (12.7mm) arborist rope, mainly for tree climbing, and i am having trouble finding an ATC belay device that fits the rope. Most of the ATC belay devices only fit up to 11mm. I do not want a figure 8 belay device because i heard they are very old and don't hold as much friction, they are also hard to maneuver. I am mainly bottom belaying, i own a ropes course in Pennsylvania and i belay my students. Please help me, i don't want a expensive device, just an ATC that will fit, please help.

As others have said, you should be using a more appropriate rope. Once you do that then you should have no problem finding a belay device to match your rope. That being said, if you insist on using a 1/2 rope then a figure-8 device may be the way to go. Yes, they are an old design and have been surpassed in holding power by other designs, but with a 1/2 static rope they should be just fine (assuming it's used properly).

You might as well use 8 or 12 belay device.

If budget is a concern, get an 8. They are fine, they just will twist the hell out of your rope. Otherwise, like others have said, get a real rope. Your 1/2" rope is beyond overkill. I know, my first rope was bought by my family, who figured bigger is better - I ended up with a 5/8" static line.

You own a ropes course and are entrusted with students, but are trying to get by with a rope you just happened to have and the cheapest device that may work? I hope this is just you screwing around on your property with some buddies and not a professional or commercial endeavor. You should probably consult someone in person who knows what they are doing and have them review your setup before someone gets hurt and you get sued.

And don't forget the humble munter hitch belay! Additional advantages of this method include wear on that rope of yours so you can buy a new one.

I am only bottom belaying, is a Figure 8 belay device good for this? If so which one is the best and holds the most friction? I heard Figure 8 belay devices were mainly used for emergency rappelling, i much rather have an ATC or a Sticht plate that could fit a 1/2 inch diameter rope. Please help!!!!

For your rope, yes a figure-8 device will be fine. Figure 8's are used for rappelling on a regular basis by "sport rappellers" and not as an emergency rap device. That's bad info. Again: there is no known ATC-style device that will accommodate that size rope.

Get professional instruction before peoples' lives are put in danger. That's the best advice you can get here.

Though even if it isn't your favorite cam you have to give your mother credit for trying. I mean most people get matching towel sets for their wedding presents!

AS I and others have said earlier: you don't need a new belay device, you need a new rope. Or you learn how to hip belay. Or use a Munter Hitch.

There is only ONE standardly available cheap belay device that will work with a 1/2 inch static rope. I've used old type Gri-Gri and it can do it but is not recommended and square Tuber's can also if they still are made.. but basically A figure 8.... PERIOD dosn't matter much what manufacturer really I am worried that you seem to be instructing others This is super basic knowledge and you are asking anonymous internet jackasses for advice? A static line for climbing? A broke ass newbie doing topropes would make some sense.. no problem if that is the case, it will work fine for top-roping but nothing further till you are ready for BIGWALL climbing and even then it's fucking heavyass overkill and a good bigwall climber would want a lighter haul line...But hell we all gotta start somewhere. But basically you are trying to use the WAY WRONG ROPE for climbing.
