B-HARKO QR1 Fixed Square Door Knob Stainless Steel 8mm Spindle Single-Sided

Product Overview

The B-HARKO QR1 Fixed Square Knob is a non-rotating door knob designed for installation on modern interior or exterior doors in commercial and residential settings. Manufactured from stainless steel, it features a square escutcheon, an 8mm spindle, and a 38mm screw spacing for compatibility with a wide range of European door hardware and lock mortises. The product's corrosion-resistant material ensures long-term performance and aesthetic appeal in both high-traffic and demanding environments.

A distinguishing factor of this SKU is its single-sided (half-set) configuration, supplied with an 8mm spindle, allowing for secure, streamlined installation on one side of the door only. This design reduces procurement complexity for projects requiring fixed knobs in paired or asymmetric door applications, and is well-suited for bulk specification in hospitality, office, or apartment renovations where durability and contemporary styling are critical.
