Double Ended Skunk Trap Trigger Design

Got a stick of 6” DWV pipe and am going to build a batch of skunk traps. I’ve made a few of these before, but only single door style with a simple push to release trigger.

Would anybody be willing to share their design for double-ended release trigger?

I have some I bought years ago from Kirk DeKalb at Advanced Trap. Best skunk traps ever, as they are so easy to use in positive sets. The trigger design is just like a body-grip trap, hangs in the center of the trap. I'll get some pics when I get a chance and post.
