From the pdf, is it to block out 4 of the 5 pinholes, so you can use just 1 size pinhole for collimation?

Interesting, thanks for the share Eizo. Is this for your 8" Edge HD? If so please let me know if you find yours is out of collimation. I've tested mine on a decreasing basis over the years because I've never found it to have a collimation error.

Yes it is, I have used it and it works, mounted it on a camera tripod, used third lowest setting, quite fun, retried it a few times to get used to it and yep, money well spent
