A bat truss clip, also known as a "hurricane tie," is a type of metal connector used in construction to secure roof trusses or rafters to the wall plate or top plate of a building's wall system. It is designed to provide additional resistance against high winds and other extreme weather conditions, such as hurricanes or earthquakes.

The bat truss clip is typically made of galvanized steel and is installed at the point where the roof truss or rafter meets the wall plate. The clip is nailed or screwed into place, and the truss or rafter is then secured to the clip using additional nails or screws.

The design of the bat truss clip features two legs that form a right angle, resembling the wings of a bat, hence the name. One leg of the clip is attached to the truss or rafter, while the other is attached to the wall plate or top plate. This creates a secure and stable connection that can withstand high winds or other lateral forces.

Bat truss clips are required by building codes in many areas that are prone to high winds or other extreme weather conditions. They are an important component of the building's overall structural integrity and can help prevent damage or collapse during a storm or other natural disaster.

The benefits of using a bat truss clip in construction include:

1. Improved structural stability: Bat truss clips help to secure roof trusses or rafters to the wall plate or top plate of the building's wall system, which increases the structural stability of the building. This is especially important in areas prone to high winds, hurricanes, or earthquakes.

2. Enhanced safety: By adding an extra layer of reinforcement to the roof trusses or rafters, bat truss clips can help prevent roof collapse and reduce the risk of injury or property damage in the event of extreme weather conditions.

3. Compliance with building codes: Bat truss clips are often required by building codes in areas that are prone to high winds or other extreme weather conditions. By using bat truss clips, builders can ensure that their construction projects meet these requirements and are in compliance with local building codes.

4. Easy installation: Bat truss clips are easy to install and can be nailed or screwed into place quickly and efficiently. This makes them a popular choice among builders and contractors who want to save time and improve construction efficiency.

5. Cost-effective: Bat truss clips are relatively inexpensive, especially when compared to the cost of repairing or rebuilding a roof that has been damaged in a storm or natural disaster. By investing in bat truss clips, builders can potentially save money in the long run by preventing costly damage to the building.
