B-Harko Platanus Door Handle Set Square Rosette Concealed Nickel Finish

Product Overview

The Klamka drzwiowa z tarczką kwadratową B-Harko Platanus (nickel finish) is a door handle set designed for both contemporary and traditional interiors, used commonly in residential and light commercial doors. Its construction features a square spindle secured with two conical hex screws for enhanced durability, and the square rosette conceals all mounting hardware, improving overall appearance. The handle is packaged as a complete set, suitable for mounting on both sides of the door.
