Our Guarantee

When installed and used correctly, Carbinge™ is rated to support 3,000# per one-foot length of the hinge material when using a steel pin.  When using other non-metallic pin materials or pins of lower diameter, the rating is reduced to 1,500# per foot. 

Carbinge Keepers™ are guaranteed not to back out (unscrew while in use) and the solder joint is guaranteed not to fail. » View our guarantee
