TD-A20 Glass Door Knob Conical Brass Chrome 30x30mm for 8?12mm Glass

Product Overview

The Gałka do drzwi szklanych stożkowa TD-A20 is a conical door knob intended for use with glass doors between 8 mm and 12 mm thickness. Manufactured with a brass core and chrome-plated surface, this hardware is used primarily in interior commercial and residential glass door installations, such as offices, conference rooms, and storefronts.

Distinct from standard round glass door knobs, the TD-A20's conical design and 30 mm x 30 mm dimensions offer a modern architectural aesthetic while providing enhanced grip. The inclusion of PVC washers at the mounting point protects glass surfaces, reducing breakage risk during installation or everyday use, which is particularly important for bulk procurement in commercial fit-outs where installation speed and damage avoidance are priorities.
