Buying advice

When buying a baby gate extension, first ensure it matches your existing gate brand and model. Measure the width you need the extension to cover. Consider whether you prefer a pressure-mount (no drilling) or hardware-mount (more secure). Extensions are generally inexpensive, so prioritize compatibility and ease of installation. Always verify that the product is from the 'Baby Products > Baby Safety' category on Amazon to avoid incorrect items.
