B-Harko Sorbus 72 WC Door Handle Patina 35?55mm Secure Set Screw Fixing

Product Overview

The B-Harko Sorbus 72 WC patina door handle set is intended for interior doors, with compatibility for both modern and traditional styles. Designed for residential and light commercial environments, it accommodates doors with widths from 35 mm to 55 mm using the included through-bolts, and can also be installed on thicker doors using additional hardware. The handle?s mounting system provides flexibility, allowing installation with both through-bolts and wood screws, and comes complete with required fasteners and an 8x105 mm spindle as standard.

What sets this model apart is its secure square spindle fixation using two conical-tipped set screws, which increases operational durability and stability compared to generic lever handles. This design minimizes loosening over time, reducing maintenance frequency and the risk of handle failure in frequently used spaces. It is especially recommended for small-scale residential developments or refurbishment projects where long-term reliability and straightforward assembly are procurement priorities.
