CRL Plymouth Series Hinges have the ability of supporting wider, heavier doors, with a maximum door weight of 140 lbs. (64 kg), and a maximum door width of 39" (1 m) using only two hinges. 

This produces a frameless aesthetic by reducing the amount of hardware needed. These hinges utilize an integrated stiffening beam to minimize clamping plate flex, resulting in exceptional holding power. They also deliver increased self-centering force, and the heat-treated stainless steel springs produce enhanced durability. 

Note: Do not use three hinges.
