Manufacturers recommendations in regard to hinge quantity, subject to doorset dimensions and or door weight; are to be followed – this to ensure warranty against excess and detrimental torsion stress incurred to any frame, that may affect frame stability and performance.
Hinges are to be cleaned, maintained and replaced where necessary, to ensure they remain free-moving; and to ensure against excess and detrimental stress to the frame(s)
- Frames are absent of damage incurred post installation (damage may remove coatings that protect the frames from corrosion, which will affect ongoing warranty). This includes also, frames that may have been damaged prior to installation but installed anyway.
