Recently I had three guys loading a couple of pickups and a trailer with T parts out of a barn. When I got home and was unloading the pickups and trailer I found 10 of these bars in the bottom of the piles. I do not know what they are but thought maybe some one on the forum might know. They are 9 inches long and screw in the back of each other you could make one long pole out of them. They are about 3\4 inches wide. If someone has a use for them they are welcome to them. I hate to just scrap them.
Sorry about the bad picture. They look to be unused.
With the threaded end and the other end rounded with a threaded hole, I might guess use 3 of them as offsets to mount a 2ed spare tire.
curtain rods for a depot hack?
Extensions for a paint roller handle...lets shorter folks paint a ceiling without stepladders.
Add as many as you need to reach the ceiling comfortably.
They sorta look like extension legs for bearing knife pullers.
Chimney sweep extension poles, so you could insert a long pole from the bottom up.
