Frequently asked questions

Can I use these clamps for welding?
Yes, Jointly™ clamps are made from stainless steel and can withstand the heat and pressure of welding projects.

Do the clamps hold materials of different thicknesses?
Absolutely. The sliding design adapts to varying material sizes and keeps the angle precise.

Are they suitable for working alone?
Yes—many customers say the firm grip and easy setup make solo projects much simpler.

Do the clamps leave marks on wood or surfaces?
Not if used properly. For delicate surfaces, we recommend placing a small buffer pad or cloth for extra protection.
