This may look like another boring joint clamp — in fact, that’s what it is. Crafters can choose from about 50 types of joint clamps to help out when making a box. But this one will clamp boards of any length, which is noteworthy. In fact, it might be worthy of picking up a few.
The clamp can handle anything under 7/8” wide. Just slip it over the boards and screw the bottom foot down till both ends grab.
Pricing is around $18 for one or $30 for a pair. Not everyone needs these high-dollar, specialized clamps — but the few that do might actually shell out for them without much haggling.
