These have been out in the winter weather all season and haven’t rusted. I am impressed. The screw is a little weird but works well. I like the product. The extra length is really nice. I would buy again.

Solid, well made, easy to use. I got them specifically for use in woodworking projects, they were perfect for my needs.

I bought them to hold together segmented wood working jobs. These are not 15.7 inch clamps - they are FIFTY INCHES long and can be reduced down to 15.7 inches at the smallest. Tightening the clamps works well but when loosening them, half the time the gear screw itself pops out. Then you have to screw it back in then out a few times until it engages with the clamp strip properly.

Yes, works fine

fit perfect on my heat shields that were rattling do to broken welds

Perfect For large vent pipes or similar. Good quality.

tension screw is an odd size. 7 mm. and Phillips drive is shallow. a bit difficult to tighten.
