Frameless Folding Beautifully Simple



fsw75 Frameless Folding

Frameless Folding To Match

FSW75 Folding Frameless System is a coordinating system to HSW75 and CSW75 for uniform sightlines. Panels fold and stack perpendicular to and within the plane of the opening and a floor track is required. For wider openings, paired panels can be added to standard configurations. Panel at the end of a chain for both FSW75 and CSW75 can be a single action door.

Narrow Continuous Rail for Outstanding Aesthetics

The FSW75 system comes standard with a 3 15/16" (100 mm) continuous top and bottom horizontal rail, allowing for a beautiful aesthetic and maximum glass. Customized rail options are available in increments of 3/16" (5 mm) from 5 1/4" (133 mm) to 7 13/16" (198 mm). To meet ADA requirements, two options are offered: a 10" (254 mm) bottom rail or a 4  3/4" (120 mm) chamfer bottom rail.

Mix and Match System Options Available for Total Design Freedom

The FSW75 uses the same head track and has the same 3 15/16” (100 mm) continuous top and bottom horizontal rails as the single track sliding HSW75 and the center pivot folding CSW75 systems. These three systems can be mixed and matched to create solutions for unique design challenges all with the same continuous look.

HSW75 Operation

Smooth and Quiet Operation

The rollers are designed using hardened steel ball bearings with glass fiber reinforced polyamide wheels with memory effect for quiet and smooth operation. Polyamide bumpers are added to each end of the roller to avoid metal to metal contact of the rollers inside the track.

No Need for Additional Structural Support for Parking

With the FSW75 there is no need for additional structural support for the parking of the panels since parking remains within the plane of the opening.

Single/Double Action End Panels

End panels can be single/double action panels with pivot points or single/double action panels with offset hinges that are capable of opening 180°. Single/double action panels with pivot points have passed 500,000 cycle testing.

Single Action Swing Panels Attached to the Chain of Folding Panels

A single action swing panel is available attached to the end of a chain of panels that folds away along with the rest of the system. For additional traffic pattern requirements, a pair of single action swing panels can be added to function similarly to French doors.

HSW75 Tubo 100

Convenient Handle Height Locking Option

A locking ladder pull integrates a locking mechanism with a profile cylinder at hand height into the tubular designed handle eliminating the need to kneel to lock the door at the bottom rail. Locking ladder pulls come in a brushed stainless steel finish.

HSW75 Hidden-Set-Screws

Added Security and Acoustical Buffering in an All Glass System

As a standard security measure, two hidden set screws per hinge are accessible only when the unit is in the open position. For projects requiring higher levels of security, or an increased acoustical barrier, NanaWall FSW75 can be configured with laminated glass.
