Concealed boxes for modular switches: sizes, prices and surface boxes

Concealed Box Manufacturer: Modular Boxes from 1M to 18M
A concealed box is the box set into the wall behind a modular switch board: it holds the plate's frame square and takes the fixing screws. We make VIZA concealed unbreakable boxes from 1M to 18M at our works in Marol, Andheri East, Mumbai, from ₹50 to ₹230 MRP, along with a G.I. sheet metal box and surface gang boxes for wiring that runs on the wall.

Key takeaways

  • A concealed box sits in the wall behind the plate; its size must match the plate, 1M to 18M.
  • VIZA concealed unbreakable boxes: ₹50 (1/2M) to ₹230 (18M); the 6M is ₹118.
  • A G.I. sheet metal box is sturdier and costs more: ₹170 for 6M (V624).
  • Wiring on the wall? A VIZA surface gang box (₹65 for 1 way to ₹265 for 18 way) replaces the concealed box.
  • On a renovation, a sound box already in the wall can usually stay.

What is a concealed box?

Every modular switch board has three parts you pay for separately: the modules (switches, sockets, regulators), the plate with its frame, and the box in the wall. The concealed box is set into the plaster when the wiring is laid, so the plate finishes flush with the wall.

Its size is counted in modules, the same as the plate: a 6M plate needs a 6M box. Get the box wrong at the wiring stage and the plate will not fit later, which is why the box is chosen before the switches.

Concealed box sizes and prices

Our VIZA concealed unbreakable box comes in eight sizes, from 1/2M to 18M. These are printed MRPs from our current catalogue:

18M ₹230
12M ₹170
8M square ₹145
8M horizontal ₹130
6M ₹118
4M ₹88
3M ₹68
1M / 2M ₹50

Printed MRPs from our current catalogue, as published in our product guides. Bars to scale; wire and labour are extra.

The 8M comes in two shapes: horizontal (₹130) for a long board and square (₹145) for a 4 by 2 arrangement. Match the box to the plate shape you will fit.

Unbreakable plastic or G.I. sheet metal?

  • Unbreakable plastic: light, does not rust, and the usual choice for homes and offices. 6M ₹118.
  • G.I. sheet metal: galvanised steel, sturdier against rough handling on site. 6M ₹170 (V624).

Both take the same plates. On most home jobs the plastic box is enough; a contractor working with heavy wall chasing may prefer metal.

Whichever you choose, the box must sit square and flush. A box set crooked in the plaster makes the plate rock and the screws strip.

Match the plate

A 6M plate needs a 6M box; choose it before the switches.

Concealed

Unbreakable plastic, 1M to 18M, ₹50 to ₹230.

Sheet metal

G.I. box for rough sites: 6M ₹170.

Surface

Surface gang boxes from ₹65 for wall wiring.

Surface wiring: the surface gang box

Where wires run on the wall rather than inside it, there is nothing to conceal a box in. A VIZA smart modular surface gang box sits on the wall instead and takes the same modules and plates, from ₹65 for 1 way (V641) to ₹265 for 18 way (V649).

Our guide to wiring systems compares surface and concealed wiring.

What the box adds to a board

Our switch board price guide prices three VIZA Cherry boards with and without the concealed box. The box adds ₹118 to ₹170 to each:

Living room 12M ₹1,468
Kitchen 8M ₹894
Bedroom 6M ₹655

Across a 2BHK in KEMPS, the concealed boxes come to ₹710 of a ₹6,302 parts bill.

Renovating: can the old box stay?

On a renovation, a sound modular box already in the wall can usually stay, which takes the box off the bill. Check that it is the right size for the new plate, sits square and flush, and is not cracked or loose.

If the old wall has a non-modular box, the wall has to be opened to fit a modular one. Our switch replacement guide covers the safe way to work on a board.

Switch off the MCB and prove the circuit dead before opening any board.
