CMC RESCUE Carabiner strength question

Post image

I’m having a hard time figuring out how strong this is.

What would it be rated to in poundage?

Thank you ahead of time for the assistance.

1kn is about 100kg or about 225lbs. (224.8).

A 27kn carabiner can take a load of about 6,075lbs before it should break or fail.

If that 27 denotes the kn rating on that carabiner, then it is a technical use (formerly light-use / personal-use) carabiner according to the 2006 NFPA 1983 standard (06ED). A T-rated carabiner would need to have a minimum rating of 20kn according to that standard. The General use carabiners according to that standard would be a minimum of 40kn.

The 2012 NFPA standard upgraded the T-rated requirement to a minimum of 27kn.
