Details To Confirm Early
01
Confirm rough opening and load path
Large and heavy door systems depend on plumb jambs, a level sill, and headers that stay within deflection limits.
02
Coordinate threshold water management
Sill pans, drainage paths, exterior slope, and accessibility requirements must be resolved before ordering.

Verify hardware and screen clearances
Handles, locks, closers, shades, and screens can conflict with trim, furniture, or adjacent panels if not coordinated.
