GI DOME COVER W/O or W THREAD SIZE: 1” or 3/4”
The GI (Galvanized Iron) Dome Cover is a heavy-duty protective enclosure cap engineered to seal, protect, and provide extra internal space for electrical junction boxes and conduit fittings. Positioned at termination points or wire splicing intersections within industrial and commercial surface wiring layouts, its raised dome design accommodates bulkier wire bundles or deep splicing connectors while shielding the internal network from mechanical damage, dust, and environmental wear.
Key Features
-
Raised Dome Space Maximization: The curved dome shape provides critical extra depth inside the junction box, allowing for neat wire management, large wire nuts, or complex splicing without crushing or pinching the cables.
-
Flexible Threading Options: Available in both Threaded configurations (with an integrated center thread for direct accessory mounting, hook fittings, or drop-rod installations) and Non-Threaded configurations (for solid, clean blank sealing).
-
Heavy-Duty Galvanized Finish: Hot-dip galvanized iron construction delivers exceptional resistance to rust, oxidation, and corrosive elements, making it ideal for harsh indoor and outdoor environments.
-
Robust Environmental Protection: Creates a solid barrier that protects sensitive internal electrical connections from falling debris, mechanical shocks, and physical impact.
-
Streamlined Security: Fits precisely over standard round conduit boxes, securing tightly with standard screws to ensure a flush, professional finish on walls or ceilings.
