3 15/16" Continuous Rail for Outstanding Aesthetics
The HSW75 system comes standard with a 3 15/16" (100 mm) continuous top and bottom horizontal rail –even on single action sliding panels– 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.
Standard HSW75 comes in sizes up to 4' 1" (1250 mm) in width and 10' 6" (3200 mm) in height for sliding panels. For all single/double action sliding panels, sizes available are up to 3' 3" (1000 mm) in width and 10' 6" (3200 mm) in height. For single/double action end panels (non-sliding), sizes available are up to 3' 7" (1100 mm) in width and 10' 6" (3200 mm) in height.

The single track sliding all glass wall offers the option of selective panels that convert from sliding to pivoting for convenient swinging entrance/egress doors almost anywhere within the span of the opening in order to meet your traffic pattern requirements. Pivot panels are available as either single action or double action sliding panels. A pair of either single or double action swing panels can be added to function similarly to French doors.
End panels (non-sliding) can be single/double action panels with pivot points or single/double action panels with offset hinges that are capable of opening 180°.
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. The locking ladder pull comes in a brushed stainless steel finish.
With the HSW75, to meet the needs of specific designs and to improve smooth operation, a true curved radius track, composed of an engineered single piece of metal, is available for gentle angle changes and ease of installation.
Intelligent Roller For Single Handed Operation
The unique "intelligent" rollers and guide technology ensure for easy, trouble-free, single-hand operation. The rollers are designed using hardened steel ball bearings with glass fiber reinforced polyamide wheels with memory effect and polyamide bumpers for quiet and smooth operation.
Patented Self-activated Automatic Panel to Panel Interlock
For straight units, the automatic floor bolt is self-activated by simply moving the panels on to one another. Once the first panel is positioned, the following panel activates the wheel and ramp assembly to automatically release the floor bolt effectively locking the panel into place without the need to lock it manually. No kneeling is required.
Patented Release System Converting Single/double Action Sliding Panels to Pivot and Vice Versa
The HSW75 has a patented release system which combines the fixing and locking mechanism for single/double action stacking doors. This patent improves the handling of turning the single/double action door into a sliding panel in a 2-step rather than a 3-step process.
Adjustable Floor Sockets
Standard to the HSW75 are eccentric floor sockets. The built-in adjustability helps to deal with tolerances and building settlements.

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

Window-door combination configurations integrate folding windows and folding glass doors within the same opening or wall plane, enabling independent control of daylight, ventilation, and entry. Commonly used for indoor/outdoor kitchens, this layout supports flexible layout design and a clean, consistent visual flow across the space.

RemoteSTACK® configurations allow individual panels on a single track to slide and park well outside the main opening. Panels move along the track and park in a designated area away from the entrance, creating completely clear openings while giving designers greater flexibility to position parked panels based on layout, circulation, and spatial needs.

Segmented configurations arrange operable glass wall panels across multiple angled or curved segments, allowing the system to follow architectural geometry beyond a straight line. This layout supports faceted walls, gentle curves, and radius designs while maintaining operability and visual continuity across residential and commercial applications.

Cornerless (Open Corner) configurations remove the vertical corner post where two operable glass walls meet at 90°, allowing panels to open in multiple directions and create a fully unobstructed corner opening. This layout enhances visual openness, spatial flow, and flexible indoor-outdoor transitions.
