Frameless Aesthetics Center Pivot Functionality


CSW75 frameless center pivot folding doors

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.

Mix and Match From Three Frameless System Options

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.

single action swing panels that fold away

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.

CSW75 continuous-rail

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.

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.

CSW75 security- hidden set of 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 CSW75 can be configured with laminated glass.

CSW75 heights and widths

Taller Heights and Wider Widths

  • Unit heights up to 10’ 6” (3200 mm) are possible.
  • Folding panels are available up to 3’ 3” (1000 mm) in width.

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.

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.

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 floor-socket

Adjustable Floor Sockets

Standard to the CSW75 are eccentric floor sockets. The built-in adjustability helps to deal with tolerances and building settlements.

CSW75  tubo

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.
