1. First, fix the top and bottom posts. Then, draw a straight line at the top between the two posts. Place the middle post on the step. Mark the drilling holes in the posts with a marker, then drill and fix the posts.
2. If the floor is already tiled, you can first drill holes with a glass drill bit. Before drilling, you can use modeling clay to create a circle around the area where the hole will be drilled to retain water and make drilling easier. After drilling with the glass drill bit, use a 12mm impact drill bit. If the base is wood, fix the posts directly with self-tapping screws.
3. Thread the wire. For wires larger than 12mm in diameter, use a special wire bending tool to bend them. Before threading, determine the position of the bend, bend it, and then thread it. You can fit the threading hole onto the wire. After the wire is in position, fix the threading hole to the post.
4. Fixing the Handrail: First, measure the area where you need to bend the handrail. Use a bending blanket to heat the area for 15-20 minutes until the handrail softens. Remove the bending blanket, place the handrail on the upright, and apply a warm towel to the handrail to help it follow the desired curve. Wipe repeatedly until the handrail is set. If scratches appear on the surface, you can remove them by wiping with the heated blanket.
5. After fixing the handrail, install the handrail end caps and threaded end caps, and tighten the set screws as needed.
