The phrase refers to exterior-grade, hinged double doors, typically featuring glass panes, available for purchase at a major home improvement retailer. These doors are designed to connect interior spaces with outdoor areas like patios or gardens. An example includes a set of outward-swinging doors with tempered glass panels, weather stripping, and a multi-point locking system, found within the doors section of a large home supply warehouse.
The availability of these doors from a large retailer offers homeowners a convenient and relatively affordable option for enhancing natural light and improving accessibility to outdoor living spaces. Historically, these doors were a sign of affluence and architectural sophistication; their current accessibility reflects the democratization of home design and improvements.
