Custom made 8 years ago when I got tired of the 70-200 2.8 drooping when mounted on a tripod or monopod.
So I went into the shop and made up this little device in about 15 minutes. Has been in my bag ever since and the plate has never rotated during a shoot!
Now you can put it into use on your lens foot if you need one too.
Pairs perfectly with the FastenR-T1
I upgraded my 10 different mounting options all to Arca-Swiss style this year, so you can save && and pick up these plates that have served me well for so many years.
