right size for the job
I was using the pre-filled 12ga flexible metallic conduit. That FMC can appear to be 1/2 in, but a 1/2 inch strap is too loose for that product. These 3/8in straps are the perfect fit and held the FMC firmly in place. Took a #8 screw without an issue, the mounting hole may even be able to take a slightly larger screw , not that it would be necessary. This is a good product and works very well. I am happy with this buy
