honestly can't believe that not one other person has asked about that.it is called a plymo vent and it is the best thing that I have ever added to my shop.they are super expensive new but used are cheep if you can find one. there is another brand called neederman that olso makes theese.all of them have different length drops,swing,and reaches. this one is hooked to a 1/3 hp fan in the attic and is the best thing for getting rid of the smoke before it fills your shop. also use it for small items to paint.put one in and you will never regret it. hope this helps. let me know if you need more info on it.Hey Erodz.....nice work....an inspiration to be sure. Can you tell me alittle about that cool looking exhaust fan in the one picture next to your boy??
Thanks,
T



ps don't forget your kids are only young once there's no do overs go out in the shop and forget everything else and do somthing creative with you kids you will never regret it.
