Very poor quality,
Verified Purchase(What's this?)
This review is from: Heavy Duty Muslin Clamps 4 1/2 inch 6 Pack (Camera)
3 of them cracked and broke at the clamps pivot point within 2 uses. This was nor stretching the jaws to the limit either, simple 1" clamping of reflectors to shelving. Save your money, not worth the aggravation.
