This is a 1/4 inch "phone" jack. I think they are called this because the switchboard operator would move a cable from 1 jack to another to connect calls, back in the early days of the telephone.
These are the same high-quality jacks that we include in our pedal kits. We are able to offer these at a more affordable price point as the name-brand jacks, with similar quality. They are really build solidly. On our search for high-quality jacks, we came across quite a few that were really low quality. We would not offer them as our "house brand" if they were not worthy.
Note that the image shows a bunch of these, to make it easier for you to view all sides. Price is for 1 piece.
