Side Folding Grilles

Open Curtain Model ESG30
Glazed Curtain Model ESG31

Side Folding Grilles and Closures provide security and access control in openings to 12' high with low headroom conditions.






The overhead track is an extruded heavy-duty aluminum section 1 1/2" wide, 1 7/8" high. Continuous recesses are extruded into profile to accept splice tongues and pins wherever track splices are necessary. Track required for curved openings has a standard 10" radius: 90°, 120°, 135°, and 150° curves are standard. Custom radii and angles are offered. Grilles can incorporate multiple connecting sections. No floor track required.


Manual push / pull operation.

Side Folding Grille and Closure Benefits:
  • Less Headroom Clearance than rolling grilles.

  • Space-saving Alignment: Curtains stack compactly (see chart) at one end of an opening or bi-part and stack at both ends, typically require stack space equal to about 25% of opening width.

Side Folding Grille and Closure Options Include:
  • Pocket Door:

Finished door and frame unit conceals stacked curtain when grille is retracted. Formed of bent steel and powder coated.

  • Locking:

Concealed cylinder-operated hook-bolt locks into full height strike channel and is operable from both sides of curtain. Cylinder-operated drop-bolt locks on intermediate members fit floor strike plates.
