Common questions,
plain answers.

All three protect and route cables. Casing 'n' capping is a two-piece channel (base and snap-on cap) fixed on the wall surface. You can open it later to add or repair wires. Conduit pipes are rigid tubes, usually concealed in walls and slabs during construction. Trunking is a larger surface duct that carries many cables (power, telecom, IT), often in offices and server rooms.

Concealed wiring in conduit is best for new construction, where pipes go into the walls before plastering. Surface wiring in casing 'n' capping or trunking suits renovations, rented spaces and anywhere you will need to change circuits later. You don't have to break any walls.

Yes, that's why it exists. MODI'S patented the two-piece system in 1984. You lift the cap to add, find or repair a wire, then press it back into place.

Use corrugated flex for tight bends, short drops to switch boxes and fittings, false ceilings, and places where rigid pipe is hard to route. For long straight runs and concealed work in slabs and walls, use rigid conduit.

We recommend it. Modi's Fit bends, couplers, tees and junction boxes are sized to match MODI'S casing and pipes exactly. That gives tight joints with no gaps and no forcing.

Flame Retardant, Low Smoke. FRLS material resists catching fire, stops burning once the flame is removed (self-extinguishing), and gives off less smoke. Less smoke keeps exits visible during a fire, which matters most in hospitals, malls, offices and high-rises.

Virgin PVC is made from fresh, pure compound. Recycled PVC is cheaper, but it turns brittle, cracks when bent, and weakens over the years. Every MODI'S product uses virgin PVC/UPVC only, and we don't run a B-grade line.

Yes. Every rigid PVC pipe and casing needs some filler, usually calcium carbonate. Used in the right amount, it adds stiffness and strength without weakening the product. The problem is overloading. Filler costs less than PVC resin, so cheaper brands add too much, and their pipes turn brittle and crack. We balance our formulation for strength, never to cut cost.

It's a deliberate choice. Black and grey plastics are usually coloured with carbon black. Making everything in ivory lets us avoid it and cut our carbon footprint. Ivory also blends with most interiors and makes dirt or damage easy to see.

If the material is good quality and properly installed, PVC wiring systems usually last as long as the wiring inside them. Virgin polymer is what keeps them from going brittle over time.

For most buildings, yes. PVC doesn't rust or corrode, and it doesn't conduct electricity. It is also lighter and quicker to install. FRLS-grade PVC adds fire safety on top of that. Some specialised industrial areas may still call for metal. Check your project specification.

An ISI mark shows that a product has been tested and licensed by the Bureau of Indian Standards (BIS) against a specific Indian Standard. For electrical products, that covers dimensions, strength and safety. Most government and PWD projects require ISI-marked material.

Casing 'n' capping and trunkings: IS 14927 Part II. Conduit pipes: IS 9537 Part III. Insulation tapes: IS 7809. We also hold CE (LVD 2014/35/EU), RoHS and FCC. Our FRLS performance has been tested at CPRI to ASTM and IEC methods.

Gauge refers to wall thickness. Heavier gauge pipes resist crushing and impact better, so they are the right choice for concealed work in concrete slabs and walls, where pipes take load during construction. MODI'S makes all three grades (Light, Medium and Heavy) from 19 to 50 mm.

Look for the ISI mark with a licence number, the IS code and the brand name printed on the product. Bend a sample: good virgin PVC flexes and recovers, while pipe overloaded with filler whitens or cracks. If in doubt, buy from an authorised dealer.

It depends on the number and size of the wires. A common rule of thumb is to fill no more than about 40% of the pipe, so wires pull through easily and stay cool. Leave spare room if you might add circuits later. Our team can help you size a project.

Yes. MODI'S conduit can be bent with a bending spring inserted into the pipe, which stops it from kinking. For sharp or repeated turns, use ready-made bends from the Modi's Fit range.

Electricians commonly use red, yellow and blue for the three phases, black for neutral and green for earth. Always follow local wiring rules. MODI'S FRLS tapes come in all of these colours.

We supply through dealers and distributors in Tamil Nadu, Maharashtra, Karnataka, Kerala, Gujarat, Rajasthan, Madhya Pradesh, West Bengal, Andhra Pradesh, Telangana, Puducherry and the Andaman & Nicobar Islands. Contact us for your nearest dealer.

Yes. MODI'S is approved by PWDs in several states. Our products are used by Indian Railways, ISRO, the Airports Authority of India, IITs, NPCIL, Apollo Hospitals, TATA and Reliance, among many others.
