B-Harko Larix 72WC Door Handle Set Patina Finish PN-EN 1906 Dual Screw Fixation

Product Overview

The Klamka drzwiowa B-Harko Larix 72WC patyna is a door handle set designed for use in both modern and traditional interior or exterior doors in residential and commercial environments. Its construction meets the PN-EN 1906:2012 standard, confirming suitability for architectural hardware applications with specific product classification 26-0030B. The handle assembly includes elements for installation on various door thicknesses from 20 mm to 55 mm, with longer spindles available for thicker doors.

A notable differentiating feature is the dual conical-ended grub screw fixing system on the square spindle, which significantly increases the handle's mechanical strength compared to standard single-screw solutions. This detail reduces the risk of handle loosening under frequent daily use, making the set especially attractive for bulk procurement in hotels, office buildings, or other multi-door fitout projects where durability and reliable function are priorities.
