Is this acceptable to code? (Pic)

Is this an acceptable way to extend off an outlet in the middle of a circuit to install a new outlet? Installing two wires under the same screw clamp. Or would it have to be pig tails? Ive come across a few instances where someone added a 3rd wire by using the push-in connector as well as both screws so my thinking is this would be better than that.

I'm not an authority on this. But I believe with this type of clamp vs hook and screw OK. But not if two wires are actually being hooked and screwed under the same terminal.

That method is much better than using the push-in but the ideal method is to tail it.

Those are clamp style. It is perfectly fine to have two wires per screw as pictured.

Will the experts confirm if this is not proper. Thanks.

The clamp style as pictured is fine.
Wrapping two wires around and under the screw is not fine.

Norm201 I am not an expert but I’ve seen in a lot of places never to loop two wires under the same screw because it wasn’t designed for more than one wire and could result in a poor connection, fire hazard.

Hi, that terminal is rated for 2 conductors, stay away from the back stab option.

Technically, it's not a code issue, but related to the instructions/approvals on the receptacle.

UL has this to say:
The Guide Information for (RTRT) states single and duplex receptacles rated 15 and 20 A that are provided with more than one set of terminals for the connection of line and neutral conductors have been investigated to feed branch-circuit conductors connected to other outlets on a multi-outlet branch circuit, as follows:
Back wire (screw actuated clamp type) terminations with multiple wire access holes used concurrently to terminate more than one conductor
https://legacy-uploads.ul.com/wp-con...NovDec2008.pdf

So assuming that receptacle is UL listed, you're using it as intended.
