Herculite door repair and all-glass entrance doors in NYC

What a Herculite door is

"Herculite" is commonly used in the trade for frameless tempered glass doors: a heavy tempered glass panel with no stiles, held by metal patch fittings or rails at the top and bottom, swinging on a top pivot and a floor closer. The name comes from a tempered glass product, but most people use it for any all-glass entrance door of this type, whatever the glass maker.

Glass replacement

Tempered glass cannot be cut or drilled after tempering, so a replacement panel is ordered to size with the holes and notches for the fittings. We coordinate the glass through a glazing partner, and our own technicians remove and reinstall the patch fittings, rails, pivots, closer and lock so the door is finished by one company. Until the new panel arrives, we can make the opening secure.
