  1. First of all you will need to measure the distance from one floor to another. You need to measure the distance from floor-to-floor not from floor-to-ceiling.
  2. You will need to calculate the height of the risers or the distance from one tread to another.
  3. Now think about the number of risers. Add the landing and you get the number of treads. Example: 15 risers – 16 treads.
  4. Determine where to attach the landing. Choose a corner of the wall opening and then use a plumb to mark the center of the post.
  5. Now position the base plate on the floor on the marked area. Use the hardware provided in the kit to secure it to the floor. Insert the pile.


  1. Add the treads by alternating them to distribute the weight evenly. Add one to the left and then one to the right until all the treads have been installed.
  2. After all the treads have been added, install the support for the newel post.
  3. Fasten the top landing into place. Use brackets and screws to secure it.
  4. Next line up the treads. They will need to overlap their front ones by 1 to 3 inches.
  5. Install vertical rods to secure the treads. The distance between each tread needs to be exactly the same.
  6. Now starting from the bottom to the top, install the handrail.
  7. Then install the landing handrail.
  8. Complete the installation by installing the newel post into place.


  • To shorten the vertical rods you can use a hacksaw
  • always wear safety goggles
  • avoid damaging the finish in the installation process.
