Like any clamp, this one can be damaged by over-tightening. This is especially true if the clamp is applied as shown above "Don't", where only the outside edges of the jaws are contacting the object being clamped. In this type of application, over-tightening will cause the sliding jaw to bind on the shaft, and could even bend the shaft. If you choose to apply the clamp in this way, user the minimum amount of pressure necessary to safely secure the clamp. NEVER USE TOOLS TO TIGHTEN THE CLAMP!
This clamp is rated at 20 pounds. A securely attached clamp will support any lamp up to 20 lbs. that is mounted directly to the baby pin of the clamp. In situations where you are reaching out from the clamp and supporting a load on an offset arm or c-stand arm, you will need to determine safe load limits for each particular application.
