Baby and pet gates are typically offered as freestanding, pressure-mounted, or hardware-mounted models. Some gates support both pressure and hardware mounting so you can choose the best option for your doorway or wall.
Expandable widths vary by model: some gates fit roughly 29.5–41.5 inches, others extend about 30.5–58 inches, and many models use extension pieces to cover even wider openings.
Gates are typically made from plastic, metal, or a combination of metal and plastic, depending on the model and design.
Several models include a walk-through door plus self-closing or auto-close mechanisms; some also offer a hold-open option for convenience when you need the gate to stay open temporarily.
Play yards are typically freestanding and highly portable, with preconnected panels that fold for transport and often a no-tools setup. By contrast, many gates require pressure fitting or hardware mounting and are less portable.
