<h1>MFSL Anchorage and Extension Kit Installation</h1>
<div class="row">
  <div class="col-md-12">
    <p>
      One of the most challenging aspects of moment frame installation is proper
      layout and placement of the anchor bolts. Incorrect bolt pattern and
      on-center placement can mean costly field fixes of the anchor bolts or
      moment frame or total replacement. Simpson Strong-Tie Strong Frame® has
      integrated templates, preassembled anchor kits and column base plates that
      help to eliminate many of the difficulties associated with anchor bolt
      placement.

      for proper installation by performing the following:
    </p>
    <ul>
      <li>
        Check to make sure the centerline marked on the template (A) runs
        parallel with the seam line (B) formed between the two pieces of the
        shear lug.
      </li>
      <li>
        Confirm the distance between the top of the anchor rods and the top of
        template plate is a minimum 4 1/2&rdquo;.
      </li>
      <li>Verify embedment depth (le) complies with construction documents.</li>
    </ul>
    <p>Once orientation is confirmed:</p>
    <ul>
      <li>
        Ensure the set of hex nuts on top of the template are cinched tight to
        hold template in place during concrete placement.

    <h2>Step 3 &mdash; MFSL Template Form Board Attachment</h2>
    <p>Prep MFSL for proper installation by performing the following:</p>
    <ul>
      <li>
        Place MFSL shear lug assemblies at the center of each frame column
        location according to measurements taken in Step 2; attach to form
        boards using duplex nails or screws.
        <ul>
          <li>
            Half moons in middle of the template can be used to pull your tape
            to confirm the measurements of the center of each frame column
            location.

      To ensure proper orientation of the MFSL, the template should be placed
      where the sticker&rdquo;s CENTER OF FRAME arrow is pointing in the
      direction of the frame opening and corresponding column. The template is
      reversible when flipped on the sticker side only.

    <h2>Step 4 &mdash; Concrete Placement</h2>
    <ul>
      <li>
        Pour and thoroughly vibrate concrete around the shear lug to ensure full
        consolidation of the concrete around the assembly. Concrete should be
        flush with top of shear lug and bottom of template.

        When the concrete has thoroughly cured to allow for construction, remove
        duplex nails or screws, unscrew the top set of four hex nuts from the
        anchor bolts to remove the MFSL template plate.
