I have a bunch of these weird t-slot connectors, and I want to buy more. They look like this : http://www.valuframe.co.uk/images/Profile5.jpg

Does anyone know what these are called, or where to buy them ?

They look like the slot nuts I got from Misumi to go in the 20x20 extrusion. They have all sorts of corner brackets and slot nuts there.

is new for me too nice, i know only L shape for 2020 (and i buy it from http://motedis.de)

They are indeed called t-matic connector. They seem to be popular in the UK and nowhere else, and are insanely expensive.

Called 80/20 in the states
