What does 'OXO' signify in glass door configurations?

In glass door configurations, the term 'OXO' refers to a specific design where there are two stationary panels flanking a central sliding panel. This configuration allows for ease of access while maximizing visibility and light entry. The stationary panels on either side provide structural support and aesthetic appeal, while the sliding middle panel enables functional movement, allowing users to enter and exit through the doorway without obstruction.

This type of arrangement is commonly used in commercial settings, where space efficiency and modern design elements are prioritized. The correct answer highlights the unique functionality of the OXO configuration, distinguishing it from other types that may feature all sliding components or entirely stationary setups.
