Stringline Clamp. It’s called a Stringline Clamp.

What’s it used for? It’s used to setup a stringline for a concrete (curb in this case) paving machine. The stringline is what the machine follows to lay the curb. There are a lot of videos online of the machines working, but not many that show the line.

Since I found it 50 feet off the street, I’m assuming when my neighborhood was built in 1981, they broke it and just threw it.

I also unearthed pieces from at least three 750ml bottles from the same area. I’m pretty sure I know why they were discarded. :)

This is the reply I got from the company.

Thanks Tom!

I found this in my back yard while tilling a few weeks ago.

It’s about 4" in length, cast of (I think) lead.

I have sent these photos to the manufacturer, so I’m hoping to here back from them about it’s specific use, and what it was a part of.

I have my theory on how it ended up 2-3" deep in my back yard, but I will wait until I get answers before I share.

It’s a ballast weight for the Binford 2000 yard crane.

I’m thinking it’s a bracket for some sort of tent/canopy.

Umbrella mount for on some type of paving equipment. Lead would make sense because it would help isolate vibrations. Bridges often have lead washers in bolted joints for vibration isolation.

GOMACO is a paving equipment company, so you are on the right track.

It’s flimsy enough that a canopy/umbrella mount makes sense.

Looks like it might be part for setting the grade for a paver. Hammer in a metal spike and use the bolt to set the height of the desired grade for a string line.

Like the blocks in the middle of the photo, holds the string line parts up.

I did Google GOMACO. Looking at it again I suspect it may be for attaching some type of guide or gauge rod to a piece of equipment. The big hole looks like it would slide over the end of a pipe and something screws into the other spots. Does the small smooth hole go all the way through the part?

Yes, there are two holes, and two set screws. I also think it’s use is to hold two rods in place set at a 90* angle. I even found someone selling the part, but there is no description.

If GOMACO doesn’t write me back, I’ll reach out to the parts supplier and ask what it is.

Wow, I think that’s it. It’s called a “stringline clamp”

Between you and Tsuter, I found the name. It’s a stringline clamp.

Nice work. I started to suspect it was something like that when I realized the big hole would have to go over the end of a pipe.

Me too. I thought I was going to have to wait for GOMACO to write me back before learning what it was.

It’s always fascinating watching stuff like that in action. Thanks for posting the video.

Also, the guy in the video: “we invented this shit!”
