A complete door unit, already assembled within a frame, available from a large home improvement retailer, simplifies the installation process. This includes the door slab, hinges, and frame, prepared to fit directly into a prepared opening. For example, instead of separately purchasing a door, frame, and hardware, one acquires a single, ready-to-install product.
The convenience of this product is a significant advantage for homeowners and contractors. Installation time is reduced, minimizing disruption. Further, pre-hanging ensures proper alignment and functionality, potentially avoiding common installation errors. Historically, door components were often sourced and assembled separately, increasing labor and requiring specialized skills. This all-in-one solution addresses those challenges.
