<h1>ATS Run Termination Details</h1>

  <h2>Top-Story Termination Types</h2>
  <p>Three top-story run termination options are provided to tailor the solution to the project’s specific needs. The option chosen will depend on construction preference or structure conditions, such as sloped top plates, truss/rafter locations that may conflict with top-plate termination and available space above top plates for the take-up device assembly. The bridge block or strap termination are often necessary or preferred when the run stops below the top plate.</p> 

  <h3 class="h4">Bridge Block Connection</h3>
  <p>The bridge block connection is an acceptable method to terminate the rod-run at the uppermost floor level. Most bridge block heights will allow the installer to tie off the rod run without working from a ladder. There is no need to worry about interference with the roof trusses or having enough room in the roof space to allow for accumulated shrinkage. One 16d (0.168") toenail to each jack stud is all that is required to keep the bridge block tight against the jack studs when shrinkage occurs in the members. Do not nail bridge block into full-height studs or sheathing to avoid gaps between the bridge block and jack studs. Check the structural plans for the required fasteners from the jack to the full-height stud below the bridge block. Nailing schedule per table below.</p>

  <ul>
    <h3 class="h4">Installation</h3>
    <li>Install full-height studs.</li>
    <li>Determine the jack stud length, number of jack studs and required fasteners unique to each ATS run (see ATS installation details).</li>
    <li>Fasten jack stud to full-height stud then add additional jack studs as necessary using the specified fastener pattern. Fastening
      requirements vary by member number as indicated in the ATS run elevation table.</li>
    <li>Determine solid sawn or multi-ply bridge block requirements unique to each ATS run (see ATS installation details) and place on
      top of jack studs.</li>
    <li>Secure bridge block to jack studs only with one toenail. Do not fasten the full-height stud to the bridge block.</li>
    <li>Drill a continuous hole in the bridge block ¼" larger than the rod diameter.</li>
    <li>Complete the take-up device assembly unique to each ATS run (see ATS installation details) per installation instructions provided
      on individual product pages.</li>
