It varies: some models require adult assembly and may need tools (listings note 'Adult Assembly Required'), while others are freestanding and labeled 'No Assembly Required' so they need no installation.
Some are designed to be portable—freestanding, lightweight, foldable, or compact when folded for easy relocation—while others are fixed-mount designs intended to remain installed.
Widths span approximately 29 in up to 205 in depending on design, and heights range roughly from 19.3 in to 34 in across the different gate types.
The listings include wall-mounted, freestanding, and pressure-mounted options across different designs.
Retractable mesh gates roll or retract so the net tucks away; folding-panel or freestanding gates fold or collapse flat or into a compact folded size for storage and transport.
Most listings target dogs; several specify small dogs or puppies, and at least one listing covers both cats and dogs.
