Key Benefits & Target Applications

Core Hardware Advantages

• Clear Optical Performance: Professional optical glass lenses ensure maximum light transmission and edge-to-edge clarity even through an extended tube length.
• Solid Brass Body: Machined from heavy-duty solid brass, providing a rigid, securely threaded assembly that will not bend or warp in deep door panels.
• Extended Door Thickness Range: Engineered specifically for deep profiles measuring 60 mm to 85 mm, avoiding the need for loose couplings or insecure stacked components on heavy doors.
• Optional UL Fire Compliance: Configurable with a UL classification to meet commercial building codes on thick fire-rated entryway doors.

Primary Application Environments

• Armored and Reinforced Doors: The exact hardware fit for heavy residential armored entrance systems and steel security doors.
• Insulated Thermal Doors: Fits deep, insulated exterior doors designed for cold storage, soundproofing, or extreme weather protection.
• Thick Commercial Panels: Suitable for industrial, banking, and high-security institution entry doors where standard peepholes are too short.
