Frameless Center Pivot Folding Systems for Space Management
Create an unlimited span of top-hung center pivot folding panels with the addition of paired panels to optimize space management or to solve unique design challenges between support columns. CSW75 does not require the use of a floor track.
3 15/16" Continuous Rail for Outstanding Aesthetics
The CSW75 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" (5mm) from 5 1/4" (133mm) to 7 13/16" (198mm). To meet ADA requirements, two options are offered: a 10" (254 mm) bottom rail or a 4 3/4" (120 mm) chamfer bottom rail.
Exterior Capabilities
CSW75 can be used in exterior applications as a windbreak. Please note that at this time, CSW75 is not rated for air and water infiltration or acoustical performance.
CSW75, FSW75, AND HSW75 combinations are possible. All three frameless systems utilize the same head track and share the same 3 15/16 (100mm) continuous top and bottom horizontal rails. Solve unique design challenges with three different systems that maintain the same continuous look.
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.
A single action swing panel is available attached to the end of a chain of panels that fold 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.
- Unit heights up to 10′ 6″ (3200 mm) are possible.
- Folding panels are available up to 3′ 3″ (1000 mm) in width.
- Single action panels hinged off bi-folding panels are available up to 3′ 3″ (1000 mm) in width.
- Non-sliding end single/double action panels are available up to 3′ 7″ (1100 mm) in width.
- End folding panel will be half the width of a folding panel.
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.
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 CSW75 can be configured with laminated glass.
No Need for Additional Structural Support
With the CSW75 there is no need for additional structural support for the parking of the panels since parking remains within the plane of the opening.
Adjustable Floor Sockets
Standard to the CSW75 are eccentric floor sockets. The built-in adjustability helps to deal with tolerances and building settlements.
Convenient Handle Height Locking
An optional 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.

Performance When Closed Matters Most
Large openings are easy to design and there are many options to choose from. When deciding on a product that best for your project, performance when closed needs to be considered

Standard glass thickness supplied is 1/2" (12 mm) tempered or (12.52 mm) laminated. To reduce glass stress, glass is clamp installed for equal distribution of weight.
An optional white interlayer can be added for the closed panels to be used similarly to a white board. Additional glazing options include low iron or decorative glass. All glazing is reduced iron. Please contact NanaWall Systems for more details.

Over 90 standard configurations for straight-forward folding systems.
Standard configurations show the most common way folding glass wall panels align across a straight opening. Panels operate in a continuous line without special conditions such as corner openings, wall pockets, or intersections, making this layout a clear starting point for planning straightforward openings.

Specialty configurations address architectural conditions that fall outside standard layouts, using custom engineering to accommodate complex geometry, structural constraints, or project-specific design requirements. These configurations enable advanced design flexibility for specialized interior and exterior applications.

The CSW75 is a frameless center-pivot folding system designed for large, flexible openings and demanding space-management applications. Its top-hung design allows an unlimited span of paired folding panels while eliminating the need for a floor track, supporting clean aesthetics and adaptable layouts.
Yes. CSW75 can be used as a windbreak in exterior applications. However, it is important to note that the system is not currently rated for air and water infiltration or acoustical performance, making it best suited for projects where windbreak functionality and flexible opening management are the primary requirements. Consult your NanaWall design team.
CSW75 offers significant design flexibility for complex architectural conditions. It can be combined with FSW75 and HSW75 systems because all three frameless systems share the same head track and continuous 3 15/16″ top and bottom rails, allowing designers to maintain a consistent frameless appearance across multiple opening types.
CSW75 supports unit heights up to 10′ 6″ and folding panel widths up to 3′ 3″. Single-action panels hinged off bi-folding panels are also available up to 3′ 3″ wide, while non-sliding end single- or double-action panels are available up to 3′ 7″ wide.
The CSW75 is engineered with rollers featuring hardened steel ball bearings and glass-fiber-reinforced polyamide wheels with memory effect for smooth, quiet movement. Polyamide bumpers are added to each end of the roller to help prevent metal-to-metal contact inside the track.
CSW75 offers anodized and powder-coated aluminum finish options, multiple handle choices, and standard 1/2″ tempered or laminated glass. For added security or acoustical buffering, laminated glass can be specified, and an optional locking ladder pull places the locking mechanism at handle height for convenient operation.
