Passage function locks are typically reversible and do not require specific handing. The lever can be installed to operate from either side. Follow manufacturer instructions for proper lever orientation during installation.
4) What finishes are available for 7KC series lever locks?
Common finishes include satin chrome, polished brass, satin brass, oil-rubbed bronze, and brushed nickel. Finish availability varies by manufacturer. Select finishes that match existing hardware for consistent appearance.
