Seismic and Hurricane Ties (HC2, HC2A, HC2.5, HC3)

ATTACHES AND secures TRUSSES AND RAFTERS TO BUILDING STRUCTURE

ClarkDietrich Seismic and Hurricane Ties are designed to provide wind and seismic resistance for trusses and rafters.

Quick and efficient, these versatile connectors can also be used for general tie-down purposes, strong back attachments and as all-purpose ties where one member crosses another.

The HC2 and HC2A seismic and hurricane ties are formed from a flat plate into an A-shaped section. The plate has a right-angle bend along its longitudinal axis to permit straddling a top plate.

The HC2.5 and the HC3 are twisted strap ties that are used to attach a rafter to the side of the top plate. All connections are shipped in equal quantities of separate rights and lefts.

Coating: G90
