Things to Consider

  • Also called “Yoke and Strap” anchors
  • For use in new masonry walls
  • For use during wall construction
  • Anchor installs in jambs and is placed between courses of block wall
  • Ships welded into throat of frame (back side of soffit in most cases)
  • The one standard size is made to work for any jamb depth
  • 1 anchor needed for each 30” of jamb (not used in head or sill)
  • 16 gauge and 10 1/2 inches long
  • Approved for use in fire rated walls up to 3 hours (180 minutes)
  • Most trouble free anchor for new masonry walls
  • Can not be lost in transit or on jobsites
  • Also uses standard base anchor for fastening to floor before wall construction


Red Flags

  • Is a little more expensive than wire anchors
  • Jamb must be concrete filled for this anchor to be most effective
  • Jamb depths over 10 ½” must receive 2 anchors (side by side) at each location
