Fits my 2020 profile and holds securely. The kit includes M5 screws with an external thread diameter of approximately 4.9mm, but the slotted holes/slots in the angle brackets are 6.2mm in diameter. That's even slightly more than the width of the T-slot in the profile (6.15 mm for me). So this mount can easily take M6 as well and M5 seems a bit sloppy to use with such a wide slot width, but their screw heads are big enough anyway (9.4mm OD) and it works.
