Single/Double Action Panels That Can Slide Away:

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°.

Single/double action panels with pivot points have passed 500,000 cycle testing.


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.

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 sliding 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.



Taller Heights and Wider Widths:

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.

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. The locking ladder pull comes in a brushed stainless steel finish.

More Options


Adjustable Floor Sockets

Standard to the HSW75 are eccentric floor sockets. The built-in adjustability helps to deal with tolerances and building settlements.


True Radius Track

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.


Matching End Caps

For added aesthetic value, smooth end caps in coordinating colors are used. The encompassed design of the end caps eliminates any sharp edges of the horizontal rails. End caps come with bumpers on one end of the panel. For corner panels, the end caps can be mitered to match.
