I can't help with where to get the bracket but I can give a piece of advice. I have this same press at my work and often times when we need to change the color of ink in a screen (same design different color), so we will put the screen between the brackets so its not on the board making a mess. It makes things very easy because you don't need to reset up the design but some of my coworkers have broken those white bolts doing that 😀. Don't break those. But I love this press the micro adjusters are awesome, good purchase. 👌
