Fetz 680 Pivot Door System

A concealed floor spring allows the pivot mechanism to remain largely hidden within the architectural assembly. This is particularly useful for modern interiors where conventional surface-mounted door closers could interrupt the visual continuity of the design.

The Fetz 680 can be used with appropriate top and bottom pivot components to create a controlled pivoting door installation.

Applications

The Fetz 680 is suitable for a range of premium interior applications, including:

Frameless pivot doors in luxury residences
Executive office interiors
Flush-mounted doors
Retail interiors
Hotel interiors
Galleries
Showrooms
Architectural partitions
Contemporary commercial spaces

It can be particularly effective where a large frameless door needs to maintain a clean and minimalist appearance.

Typical System Components

A project-specific Fetz 680 installation may include:

Fetz 680 floor spring mechanism
Top and bottom pivot fittings
Optional hold-open module
Installation tools and templates
Technical data and mounting instructions

Designed for Minimalist Architecture

The Fetz 680 complements architectural concepts based around flush doors, concealed frames, shadow gaps and frameless interiors. By keeping the floor spring concealed, the system helps preserve the uninterrupted appearance of the surrounding architecture.

It is a practical choice for architects, interior designers and fit-out contractors specifying premium pivot door hardware for contemporary projects.
