Someone on this forum mentioned many years ago, they are fuse holders or fuse clips

According to two different AI searches the answer came back as a no.....however I guess a hobbyist somewhere may have found an alternate use.

No, Newman roller frame alignment clips do not appear to have been used (or designed) for anything else beyond their specific purpose in screen printing with Newman Roller Frames.These clips—small spring-loaded or clip-style tools sold in packs of 6—are manufactured by Stretch Devices (the company behind Newman Roller Frames, often under the Newman brand name). Their sole documented function is in the screen stretching process for textile and graphic screen printing.

All sources (product listings from Lawson Screen Printing, Performance Screen Supply, Nazdar/SourceOne, Reece Supply, Stretch Devices' own accessories page, YouTube tutorials on stretching Newman frames, and forum mentions on Reddit/T-shirtforums) describe them exclusively in this context. There are no mentions of repurposing them for other applications—like general clamping, alignment in woodworking, model building, photography, or any non-screen-printing use.

Pierre is on CCI Nexus emulsion now.  If you have run PHU 2, the data numbers are almost identical.  48% solids.  It's great for plastisol, wb, d/c.  Long runs or D/C you can add diazo.  Nothing really changed with exposure as far as I know.  It did however shore up pin holes that were becoming a problem with some emulsions.

CCI LXP is optimized for LED.  You can get 4-5 sec exposure on an I Image STE and most LED units.

CCI LXP is awesome, we used it for many years.

Eco Frame panels in a roller would be great.
