Hettich TopLine 120 SiSy (Silent System)

Overview

The Hettich TopLine 120 SiSy is a heavy-duty, soft-close sliding door track system designed for room divider applications. It is built to carry heavy inset sliding doors quietly, using Hettich's Silent System (SiSy) soft-close mechanism to prevent slamming and reduce noise during operation.

What It Does

TopLine 120 SiSy is a running/track system for sliding doors used as room dividers. It supports heavy door panels and closes them softly via an integrated damping mechanism, rather than relying on a hard stop. This makes it suited for partition walls, sliding room dividers, and large inset door panels in residential or office interiors.

Who It Helps

Architects and interior designers specifying room divider or partition systems that need to handle heavy door weights.
Carpenters and fabricators building custom sliding room dividers who need a rated, heavy-duty track and soft-close mechanism.
Homeowners and office fit-out buyers looking for a quiet-closing, heavy-load sliding door solution rather than a standard glide track.
