Parapet Holder for Lightning Protection system – ARK Make by DFMHUB
In modern lightning protection system (LPS) design, the parapet holderfor lightning protection systems plays a mission-critical role in ensuring mechanical stability, electrical continuity, and long-term durability of down conductors routed along building parapet walls. The ARK Make Parapet Holder by DFMHUB is engineered specifically for Indian construction practices, climate conditions, and IEC 62305 lightning protection standards, making it suitable for consultants, EPC contractors, and industrial facility owners seeking technically compliant and site-proven solutions.
Unlike generic clamps or improvised supports, this parapet holder is purpose-built for lightning conductors, ensuring correct spacing, vibration resistance, corrosion protection, and compatibility with copper, GI, aluminium, and copper-bonded conductors widely used across India.
What Is a Parapet Holder?
A parapet holder is a mechanical support accessory used in lightning protection systems to securely fix the down conductor or air termination conductor along parapet walls or rooftop edges, maintaining:
Correct conductor routing
Prescribed separation distances
Mechanical stability under wind load
Electrical continuity during lightning discharge
In IEC 62305-compliant LPS design, conductor fixing accessories such as parapet holders are essential components, not optional hardware.
Why Parapet Holders Are Critical in Indian Buildings
India’s built environment presents unique challenges for lightning protection:
High lightning density zones (Kerala, Odisha, West Bengal, Maharashtra, Telangana)
Extreme UV exposure on rooftops
Heavy monsoon rainfall & humidity
Coastal corrosion environments
Concrete parapets with varying thickness & finishes
The ARK Make Parapet Holder is designed to withstand these real-world Indian site conditions without compromising conductor integrity or safety.
