Steps for installing a fire escape ladder:

  • Take the template that comes with the fire escape ladder and tape it to the wall centered beneath the window and 6 inches below the window stool.
  • Use a level to ensure the top of the template is perfectly level.
  • Cut along the dotted lines on the template with a utility knife.
  • Remove the template and finish cutting through the drywall along the scored lines.
  • Pull out the severed piece of drywall and cut away any insulation from the rectangular hole.
  • If there’s a stud in the opening, cut it out with a reciprocating saw.
  • Make the first cut through the stud 3 inches below the bottom of the opening.
  • Cut the top of the stud flush with the top of the opening.
  • If the rough sill protrudes into the opening, make a series of closely spaced cuts into the underside of the sill, then chop out the waste with a hammer and chisel.
  • Cut short pieces of 2x4 to fit inside the wall to provide solid nailing for the fire escape ladder. Secure the pieces with 3-inch screws.
  • Press a thin piece of foil-faced insulation into the opening to act as an insulating thermal break.
  • Remove the fire escape ladder from its metal box, then set the box into the opening.
  • Bore a ⅛-inch-diameter pilot hole through each of the four mounting holes.
  • Attach the box to the opening with four ¼-inch x 2½-inch lag screws. Secure the fire escape ladder with the two top screws.
  • Drop the ladder out the window, and then have someone outside climb up two or three rungs of the ladder.
  • While the person remains standing on the ladder, check the lag screws inside the metal box to ensure the ladder is being held securely in place.
  • Retrieve the ladder, fold it up, and tuck it inside the box.
  • Snap the protective cover onto the box to conceal the ladder.
  • Patch the wall with spackling compound, then prime and paint.
