Is this the right one for you?

Check these three things before you order:

• The run ends here - only one conduit enters the box.
• Your conduit is 20 or 25 mm outside diameter - the fitting size is the conduit size.
• Fittings to IS 3419 are wanted or specified.

Why choose the Polycab PVC Circular Box - Terminal (1 Way)

• One conduit entry - the right layout for the end of a conduit run
• Screw-on round lid - comes off for wiring, jointing and inspection; spare lids are listed separately
• Made to IS 3419 - the Indian standard for fittings for rigid non-metallic conduits
• Sized for 20 and 25 mm conduit - the entries take Polycab conduit of the same outside diameter
• Part of the full Polycab conduit system - pipes to IS 9537 Part 3 and matching boxes, bends, tees, elbows, couplers and saddles

Installation notes

Fix the box first, then cut the conduit to length and push it fully into the entry; in concealed work the joint is usually made permanent with PVC solvent cement.

Set concealed boxes so the lid sits flush with the finished plaster or ceiling - joints must stay accessible, so never plaster over a lid.

Make joints inside the box with proper connectors, keep the earth continuous, and close the lid once the wiring is tested.

Where it is used

• Ceiling and wall light points in homes, flats and offices
• The last point of a lighting branch
• Bracket and outdoor light points on conduit runs
• Concealed and surface conduit wiring in shops, schools and hospitals

Frequently asked questions

Where is the terminal (1 way) circular box used?

At the end of a conduit run - a ceiling or wall light point, or the last point of a branch, where the wires stop and connect to the fitting. For a point in the middle of a run use a through box; to turn a corner, an angle box; to branch, a tee box.

Is there a non-ISI version of this box, and what is the difference?

Yes. This is the ISI version: rigid PVC, made by Polycab to IS 3419 (the Indian standard for fittings for rigid non-metallic conduits), and it can be joined to PVC conduit with PVC solvent cement. Polycab also makes a non-ISI polypropylene (PP) terminal (1 way) box with the same entry layout, sizes (20 and 25 mm) and packs; it is not ISI marked and is a push fit, because PVC solvent cement does not bond polypropylene. Choose ISI where the specification, the consultant or the authority asks for ISI-marked fittings; the non-ISI box suits jobs where that is not required. If you wish, we will quote both so you can compare before you decide.

Which sizes and codes are available for the terminal (1 way)?

20 mm - CFT0120001; 25 mm - CFT0125001.

How is it packed?

20 mm - 50 per pack, 700 per transport pack; 25 mm - 40 per pack, 560 per transport pack. Tell us the number of pieces or packs you need.
