Zapornica Drzwiowa Chain Door Restrictor Chrome Finish 85mm

Product Overview

The Zapornica drzwiowa (łańcuch) CHROM is a door chain restrictor used to provide basic security for residential and light commercial environments. With its chrome finish and a width of 85 mm, this chain type restrictor allows partial opening of doors, enabling occupants to identify visitors while maintaining partial security. It is typically installed on apartment or house entry doors.
