Hettich Onsys 4447 Auto-Closing Door Hinge with Mounting Plate & Cover Caps

Overview

The Hettich Onsys 4447 is a non-silent, auto-closing cabinet door hinge from Hettich's Onsys hinge range. It uses an auto-closing mechanism that pulls the door shut without a soft-close cushion, and it opens to a 105° angle. Each set ships with mounting plates and cover caps, so it's ready to install on cabinet doors without sourcing separate hardware.

What It Does

The hinge attaches a cabinet door to its carcass and automatically closes the door once it's pushed within a certain range, without needing a full manual push-to-close. It's built for everyday cabinet use where consistent, reliable closing matters more than a soft-close feel.
