Clamps: FAQ

How do I choose the right size clamp for my documents?

Always check the capacity in millimeters or the number of sheets specified in the listing. Sizes typically range from mini (15mm) to jumbo (51mm), so measure your document stack thickness before purchasing.

How can I distinguish between high-carbon steel and standard alloy?

Look for 'tempered steel' or 'anti-rust coating' in the product specifications. High-quality clamps feature a matte or smooth powder-coated finish that prevents corrosion and ensures long-term tension.

What indicators suggest a clamp will maintain its tension?

Check for spring-steel construction and reinforced lever arms. Review seller feedback for mentions of 'strong grip' or 'retains shape' to ensure the clamp won't lose its hold after repeated use.

Will bulk orders of metal clamps arrive damaged or bent?

Top-rated sellers use rigid plastic storage boxes or reinforced cardboard packaging to prevent crushing during transit. Look for listings that specifically show 'boxed packaging' in the product photos.
