HCA Hinge Connectors

Share This Post:


Hinge connectors are designed to transfer loads between two beams aligned end-to-end through a combination of bearing plates, side plates and bolts. In addition to supporting vertical loads, hinge connectors can also be specified with additional slotted bolt holes to resist horizontal loads as part of a continuous load path. They can also be ordered to accommodate dapping or notching on the top of the beam. See Hinge Connector Specifier Guide.
