GI 3 WAY BOX W/O or W THREAD SIZE: 1” or 3/4”
The GI (Galvanized Iron) 3-Way Box is a heavy-duty tee junction box engineered for multi-directional electrical routing and mid-line circuit branching. Positioned at T-intersections within industrial, commercial, and domestic surface wiring layouts, it provides a safe, accessible enclosure for splitting a single main conduit run into two separate paths while shielding the electrical network from mechanical damage, dust, and environmental wear.
Key Features
-
Three-Way Branching Design: Features three precision-engineered openings arranged in a “T” configuration, making it the ideal enclosure for splitting circuits, dropping lines down to switches or outlets, or branching power networks across ceilings.
-
Removable Access Cover: Equipped with a secure, bolt-on top plate that grants direct access to the interior chamber, allowing for effortless multi-directional cable pulling, wire splicing, and quick safety inspections.
-
Heavy-Duty Galvanized Finish: Hot-dip galvanized iron construction delivers exceptional resistance to rust, oxidation, and corrosive elements, ensuring long-term durability in both indoor and outdoor industrial environments.
-
Flexible Threading Options: Available in both Threaded configurations (for rigid, airtight screwed pipe joints) and Non-Threaded configurations (for quick slip-on, set-screw, or clamp assemblies).
-
Robust Mechanical Protection: The solid molded iron casing protects sensitive internal splices and connections from severe mechanical shocks, high vibrations, and thermal stresses.
Configuration Selection Guide
| Size & Thread Type | Standard Commercial & Industrial Applications |
| 3/4” (20mm) / Without Thread | Fast-assembly T-branching for standard commercial lighting circuits, workshop wall drops, and domestic surface-mount wiring networks. |
| 3/4” (20mm) / With Thread | Secure, moisture-resistant T-junctions for small machinery power distribution, outdoor security grids, and utility room piping branches. |
| 1” (25mm) / Without Thread | High-capacity three-way enclosure for main sub-panel runs, data center server arrays, and commercial distribution lines requiring quick slip-on assembly. |
| 1” (25mm) / With Thread | Heavy-duty, vibration-proof T-intersections for main industrial machinery inputs, factory floor heavy trunking networks, and high-load primary power distribution. |
