These clips are my second favorite clips. I say "second favorite" because they are "too" strong and sometimes I shift my boards so that my glued boards end up being a little "staggered". Also, they're a little harder to open. I know - it's all downforce quality! Just saying they're not my favorite because I usually glue 2 1/8" sheets together (for our laser cutting and engraving business). These clamps work much better on thicker boards though, so I keep them for this purpose and use my smaller clamps for my 1/8" thick boards. I also hang them on this cafe bar so I can just pick up the clip and All in all I recommend these! And at least they will make your arms stronger just by opening and closing them! LAUGH LOUD. So bonus, arm weights AND work braces ;)
