Key Benefits & Target Applications

Core Hardware Advantages

• Deep Profile Adaptation: Specifically engineered for exceptionally thick doors measuring 50 mm to 90 mm, providing a secure, flush installation without requiring expensive brass couplings.
• Large 30 mm Wide-Vision Head: The oversized 30 mm head maximizes light capture and provides an exceptionally wide, clear viewing field for deep-profile doors.
• Anodized Silver Aluminum Finish: The anodizing process creates a highly durable, corrosion-resistant silver surface layer that mimics standard chrome plating while offering high resistance to scratching and tarnishing.
• Cost-Effective Project Specification: Constructed from lightweight aluminum, offering a highly economical alternative to solid brass for large-scale construction projects and budget-conscious developments.

Primary Application Environments

• Thick Armored Entry Doors: The ideal, cost-effective hardware match for thick residential armored security doors and reinforced entryway systems.
• Insulated and Double-Panel Doors: Fits deep, insulated exterior doors used for cold storage, thermal protection, or acoustic soundproofing.
• Heavy Commercial Openings: Suited for industrial facilities, storage areas, and commercial buildings utilizing deep-profile door panels.
• Budget-Conscious Commercial Builds: Allows contractors to meet heavy-duty structural thickness requirements without the premium cost of solid brass hardware.
