It’s probably not something you have an immediate use for, but it’s definitely worth keeping a simple bar clamp in your tool box, and this one is down to just $8 today, an all-time low.
By way of example, I had a piece of MDF on my TV console split during a move last year, and used a similar clamp to squeeze the sides together over some wood glue until it dried. I admit I haven’t used it since, but I’m sure I will some day.
