I have a plumber friend that made me 4 of them...They are 5 feet long (he cut a 10 foot in two)...He used a 2 way split at the bottom...They hold about 20 pounds of corn, deer will eat out of them in just a day or two...At the top, he used a screw on top and drilled 5-6 1/4 inch holes in the bottom cap so water will drain out...

I used to use mechanical feeders, 2 got stolen...I see more deer during the day with the pipes, it takes awhile for deer to get used to the mechanical going off..
