Very good price, works well.

Nice diecast fittings. They do what they are supposed to.
Being a Diecast metal, it is prudent to debur the box end to avoid damaging wire insulation when pulling wire through them.

3/4 ss connector
Your average ss connector cast in India so quality is ok.

These are marked 3/4 EMT and they are not for 3/4 inch EMT they are for 1/2 inch not 3/4 inch EMT
I ordered specifically 3/4 inch EMT connectors these connectors are marked 3/4 inch and they are not, they are 1/2 inch EMT connectors not 3/4 inch EMT connectors.

Incorrectly labled.
While the container was labeled as 3/4" EMT connector, the product is for 1/2" EMT. I suspect this is simply a mislabeling issue.
