2" RGS

Sorry I believe I've asked this before but will save responses for reference. Don't look at a lot of duct bank work.

Have about 700' of 2" RGS feeding 13 park poles. Will have 1 elbow at each pole(there's a box by the pole so it's not in/out) and then some out in the field. Tough to know the exact routing(pic below as example) but obviously there will be bends. What determines whether you would use factory elbow or bend? Thanks.

Site conditions and trenches can vary so if offsets and kicks in the pipe are being used you would probably bend them. For only 90's you could bend or use manufactured elbows. Manufactured elbows require the use of nipples to make them longer which typically are field threaded.

Thanks. Can you explain why pre-fab elbows require nipples to make them longer.

I can bend a 90 that comes up 54.5". Prefabs only come in certain lengths.

Sure, let's say you need a 48" elbow to enter a hand-hole, box, etc. You use a manufactured elbow which is say 18" long. Now you need to cut and thread a nipple to make up the 30" that you're short. With a bender you can just bend a 48" elbow.
