GI Metal Concealed Box: The Part Nobody Sees, But Every Electrician Gets Right
Concealed wiring looks clean and professional on the wall. That clean finish depends entirely on what is embedded inside the wall before the plaster goes on. A loose, poorly fitted or wrong-size concealed box will cause the switch plate to wobble, sit crooked or not align with the frame at all. Fixing it after plastering means breaking the wall open again.
Anchor and Legrand Arteor GI metal concealed boxes are made from galvanized iron for long life and corrosion resistance inside wall cavities where moisture can accumulate over years. Galvanized iron holds screws firmly and does not flex or crack the way plastic boxes can under the torque of repeatedly tightening switch plate screws.
Available from 1/2 module for a single switch point all the way to 24 modules for large switchboards with multiple switches, sockets, USB outlets and fan regulators on the same plate. Anchor boxes cover the range from 1/2 to 18 modules and Legrand Arteor boxes from 1/2 to 24 modules. Both are ISI marked and made in India.
Compatible with Anchor, Legrand, Goldmedal, Schneider and most standard modular switch plate dimensions used in India.

💬 FAQ Section
Q1. What is a GI metal concealed box? A GI (Galvanized Iron) metal concealed box is a rectangular steel enclosure that is embedded into the wall during construction or renovation. It provides a fixed, sturdy housing into which modular switch plates, sockets, dimmers and other electrical accessories are mounted. The galvanized iron construction resists corrosion from moisture inside wall cavities and provides firm support for the screws that hold the switch frame in place.
Q2. What module size concealed box do I need? Module size refers to how many standard modular electrical accessories the box can hold. A 1M (1 module) box fits a single switch or socket. A 4M box fits four modules side by side. A 6M box is commonly used for a 3-switch 3-socket combination. For large switchboards with 8 or more accessories, 12M, 16M or 18M boxes are used. Always confirm the module count of your switch plate before ordering the box.
Q3. What is the difference between Anchor and Legrand Arteor concealed boxes? Anchor GI concealed boxes are designed for use with Anchor by Panasonic modular switch plates and are widely compatible with most Indian brands. Available in 1/2M to 18M. Legrand Arteor metal flush boxes are specifically designed for the Legrand Arteor and Mylinc modular range and are available in 1/2M to 24M. Both are ISI marked and made in India. If you are using Legrand switches, use Legrand boxes for guaranteed fit and alignment.
Q4. Can I use an Anchor concealed box with Legrand switches? Not always reliably. While dimensions are similar, modular switch plate screw hole positions and frame alignment can vary between brands. For guaranteed fit and clean finish, always match the box brand with the switch plate brand. Use Anchor boxes with Anchor switches and Legrand Arteor boxes with Legrand switches.
Q5. What is HSN code for concealed boxes? Anchor GI concealed boxes carry HSN code 8536 and Legrand Arteor flush boxes carry HSN code 8538. Both attract 18% GST under these HSN classifications. When placing bulk orders for commercial or industrial projects, confirm the HSN code on the invoice for input tax credit (ITC) purposes.
Q6. What depth concealed box should I use? Standard Indian modular switch boxes are typically 35mm to 40mm deep for regular switch and socket points. Deeper 50mm or 60mm boxes are used for points that need to accommodate more wiring slack, such as AC connection points or DB-adjacent outlets. Check the depth specification on the product page before ordering for specialized applications.
