FRONTLINE FALL PROTECTION COP01 Concrete and Steel D-Ring Reusable Anchor Plate | Concrete Walls,Ceilings,Columns | ASTM rated steel | OSHA & ANSI Compliant

I used them in a concrete slab to anchor a tiny house on our farm. They worked great with large turnbuckles and I am confident the tiny house will be secure in a windstorm. I think they would be great for any application where you need something secure. I used a 1/2 inch concrete hammer drill bit and the ancors fit perfectly in the whole I drilled about 3.5 inches deep.

Nice having everything in one package. Thanks guys .

Rather heavy duty and easy to install, particularly after once I borrowed a hammer drill to get through my concrete floor which is where I mounted 4 of these - to lock things down so things don't walk off. Specs on the plates are good. Construction, cleaning and painting weren't the greatest - there were some rough welds and they were shipped plastic wrapped so there was some coating damage. It'll be fine, but they could have been better protected.
