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 1 of 6: Determine Gate Placement
Before drilling, decide on the precise mounting points. For the wall side, hold the gate at the desired height and mark the screw hole locations. For the banister side, use the banister mounting kit's template or the gate's hardware as a guide to mark the attachment points, taking into account any angled surfaces or required spacing for the mounting kit.
