What happens in this clip
With the gate temporarily held in place, use a pencil to mark the exact position of the four wall cups on the wall or door frame. Also, mark the center point within each wall cup where the screw will go. After marking, remove the gate from the opening. Then, use a drill to carefully punch holes at each of the marked screw points.
Goal: Create pilot holes for wall anchors and screws.

About the full video
This DIY project provides step-by-step instructions for securely hardware mounting a Cumbor baby gate, which is highly recommended for safety, especially when installing the gate at the top of stairs. The process includes unpacking components, measuring and adding extensions if needed, marking and drilling holes, installing wall anchors and cups, tightening the gate, and finally, testing its functionality.
Step 3 of 6: Drill Pilot Holes
Select a drill bit that is slightly smaller than the diameter of the screws provided with the baby gate. For each marked screw position, drill a pilot hole into the solid wood. The depth of the pilot hole should be sufficient to accommodate the length of the screw, but not so deep that it compromises the integrity of the wall.
