Specification First, Customization Second
For architectural door hardware, customization goes far beyond surface aesthetics. Dimensions, tolerances, and mechanical compatibility dictate whether a product will install seamlessly and perform reliably within an existing door system.
For this reason, all OEM/ODM projects prioritize the technical alignment of:
Lock case dimensions & Backset
Center distance & Door thickness
Cylinder compatibility & Spindle dimensions
Fixing-hole positions & Handing
Material composition & Surface finish treatment
Installation method & Market-specific regulations
Providing these specifications at the quotation stage allows our team to optimize product configuration, sample accuracy, and packaging structure before mass production begins.
