General Considerations: What fire rating are you trying for?
• Be sure to select the appropriately UL listed product for the application
• Check that your job site conditions are the same as the UL Listing

Floor Installation Prep: Are your concrete surfaces properly prepared?
• Surface mounted covers require a square, clean joint
• Blockouts must be level for recessed covers
• Set the substrate at the correct elevation prior to the fire barrier installation

Wall Installation Prep: Are your substrates finished correctly?
• Drywall must be installed on the inside of the joint
• Joint edges must be parallel to one another
• Be sure the proper blocking connection points are made, if applicable
  (Typically needed in 2 hour rating situations)
• Be mindful of floor fire barriers above and below for proper transitioning
