Learn MoreHerculite Door Expertise
Herculite doors represent the pinnacle of commercial glass door design, offering maximum transparency without the visual interruption of door frames. These heavy tempered glass panels, typically 1/2 inch or 3/4 inch thick, are mounted using precision patch fittings that clamp directly to the glass edge and connect to floor closers, top pivots, and lock mechanisms. The result is an all-glass entrance that provides unobstructed visibility into and out of the space, creating the modern, professional appearance that high-end offices, retail boutiques, and financial institutions demand.
The hardware that supports Herculite doors is the key to their performance. Patch fittings from manufacturers like Dorma, CRL, and Pinnacle are precision-machined metal pieces that bolt through pre-drilled holes in the tempered glass. Floor closers from Rixson and Dorma provide controlled closing speed, backcheck to prevent slamming, and latching action. Lock rails house the locking mechanism at the mid-height of the door. All of these components require expert installation and periodic adjustment to maintain safe, smooth operation.
