The present invention is a channel-shaped connector for connecting a first building structural member to a second building structural member in conjunction with fasteners and an anchor member to resist forces on buildings imposed by earthquakes, hurricanes, tornadoes and other similar cataclysmic forces. A connector constructed in accordance with the present invention consists of a back member formed to interface with the fasteners for attaching the back member to the first building structural member, a first side member connected to the back member, a second side member connected to the back member, and first and second anchor receiving members. Both the first and second anchor receiving members extend laterally between the first and second side members, and both the first and second anchor receiving members are connected to the first and second side members. The first and second anchor receiving members are disposed so that a space exists between the first and second anchor receiving members for receiving the anchor member therethrough for attaching the connector to the second building structural member.

DETAILED DESCRIPTION The object of the present invention is to provide a connector that better withstands tension forces than the prior art while still being economical to produce and install.
A further object of the present invention is to provide a connector that accommodates variations in the position of the anchor member parallel to the face of the first building structural member to which the holdown connector attaches.
This object is achieved by forming the connector with a wide space for receiving the anchor member.
The object of making a holdown that is economical to produce is achieved by utilizing a design that can be formed from galvanized sheet metal on standard die press machinery, eliminating costly secondary operations such as painting and welding.
The object of making a holdown that is easy to install is achieved by utilizing a design that is amenable to current building practices.
These and other objects of the present invention will become apparent, with reference to the drawings, the description of the preferred embodiment and the claims.
