I see the Superior Construction trailer in the background of one of your pics. They were the last company I worked for before going out on my own. I didn't realize they were down in TN.
Looks like we will have something in common then haha. I came to Superior from Walsh when my old Project Manager (worked for him at Walsh and he went to Superior) offered me a spot in Nashville. Superior is relatively new to the Nashville area. We are on our third project here. This one is at the airport and will be about 4-5 years long. I don't think I will see the end of it. I am a project engineer for them, but being non union I get to do a good bit of the field stuff as well when we are self performing.
I like the round conis. I haven't used PVC to guide them in though. I've usually used scrap flashing that is always laying around my truck. Ill have to pick some up!
I always take the trap in with me when I go to get more to make sure it fits. With the different schedules and types you never know if the dimensions are going to be the same.
I cut this one with a wedge on it to fit in the corner.
I have a friend that does a similar setup for mink trapping. I believe he used 6" pipe so he didn't need the coupler section. Get a piece of pipe a couple feet long, add the coupler if needed, and stick it in the bank. Mink love checking out every ditch pipe/tile
