Hettich Sensys 8645i Thick Door Hinge with Mounting Plate

Overview

The Hettich Sensys 8645i is a soft-close furniture hinge built for thick cabinet doors, supporting door thickness from 15 mm to 24 mm. It ships as a pair with mounting plates and is available in Inset and Overlay door applications. The hinge is made of nickel-plated steel and opens to 110°.

What It Does

The Sensys 8645i integrates soft-close technology directly into the hinge body, so cabinet doors close gently and silently without needing a separate soft-close damper. It is designed for kitchen and furniture cabinets where doors are thicker than standard (15-24 mm), using a screw-on mounting plate for installation.
