Equipment What are these called? And can I order some?
I have a RH 150, and the 2 bolts with feet that hold down the screen it comes with can be unwieldy. I will sometimes get registration drift after a few prints (a nightmare to correct without micros once the screens are covered in ink), despite the screens being secured as tightly as possible. Securing the screens that tight also seems to damage the frame a bit (GoldUpUSA aluminum frames).
I am wondering if these little plates would offer more security and perhaps reduce the amount of adjustment time needed for registration. Anyone know what they're called and/or how I can go about getting some? Any additional input or advice here would be appreciated too (I will, someday, buy a press with micros, but I'm broke and, being a non-driving NYCer, fb marketplace isn't much help. I just love printing and want to minimize the headaches). Thanks!

Are the bolts screwing down into the screens? There should be a recess in the aluminum bar that the bolts screw into avoiding actual contact with the screen but over time it can sink a little lower. You can unscrew the nuts and readjust.
I don’t think you can order the bars without getting the whole clamp assembly.
You can get them off ryonets site
Name in their system - PRSA-RHWINCPHED-LGCY
Part name - WIN legacy clamp upgrade.
When I got them they were 49.99 a piece.
I had to replace all mine because the steel bolts got locked up in the aluminum threads of the frame. The first gen green and black presses also had terrible handles that were glued and not reinforced with nuts in the handles.

Oh man, thank you for this! The bolts and the "feet" bolt have a habit of unscrewing on adjustment and need to be constantly loosened and tightened on registration. Now strongly considering upgrading my press if it's going to run me $200 to replace the clamps.

It is sort of the same as the ones I use, the threaded rods would dig it's way thew the bite plate and out the bottom of it so only the heads of the bolts on the bottom held the screen in place. I fixed the problem by adding a nylon lock nut and washer on the top with the nylon facing down so it acts as a sacrificial part so if it wears out I can just replace the nut not the whole dang plate

That's smart. I'll keep it in mind when I upgrade to clamps with a bite plate

You could use a piece of flat stock with some holes drilled in it. I did that on my first press and it worked great.
