Frequently Asked Questions
Do these come with the clamp shown in the photos?
No. This product is a set of adapter blocks only. You need to use your own existing quick-grip style clamps with them.
Will these fit my specific brand of clamps?
They are designed with a universal slot to fit most standard 6-inch quick-grip bar clamps, and similar popular brands found in hardware stores.
How many do I need for a project?
These must be used in pairs to clamp one corner effectively. This 4-pack provides enough adapters to clamp two corners simultaneously. To clamp all four corners of a box at once, you would need two sets (8 pieces total) and four clamps.
