Shipped Broken Down For On-Site Assembly
The frame and door panels are pre-drilled with hardware and weather stripping already attached. The frame is broken down into its four pieces (header, two jambs and threshold) and panels are shipped individually. Lanai Doors⢠provides detailed installation guidelines and we do not require the use of specific installers.
No Sun Exposure Warranty
Lanai Doors⢠does not warranty a wood panel from warping which is subject to direct sun exposure. The industry rule of thumb is that a southern and western exposure requires 100 percent overhang (eight foot door requires an eight foot overhang); eastern and northern exposures requires 50 percent overhang.
