PVC Trunking Angles, Tees and Couplings for Corner Runs: Choosing the Right Internal, External and Flat Fittings

On a surface wiring job everyone looks at the trunking, but the client's eye lands on the corner. A run can be straight, level and well fixed and still look amateur when every turn is a hand-cut mitre with an open joint. That is why careful contractors order the moulded internal angle for PVC trunking, external angle for PVC trunking and flat angle for PVC trunking before the first length goes up.

Cut corners cause real trouble on site. Open gaps let dust and insects into the channel, a badly cut mitre leaves the cover rocking instead of clipping flat, and every sharp joint is one more place where cable insulation can be damaged during a pull.

The internal angle for PVC trunking turns a recessed corner where two interior walls meet, while the external angle for PVC trunking wraps a projecting corner such as a column. The flat angle for PVC trunking handles the third case, where the run stays on one surface but changes direction, rising up a wall towards a ceiling drop.

Branches are made with a flat tee for PVC trunking, letting a spur leave the main run without exposing cable. Straight lengths are joined by a coupling for PVC trunking, sold in many catalogues as a coupler for cable duct, and the open end is closed with an end cap for PVC trunking or a stop end for cable duct.

Sizes have to be ordered together. Profiles such as 25x25, 40x25, 60x40 and 100x50 each have their own moulded angle, tee and coupling, and a fitting made against another factory's profile will never clip cleanly.

G AND N FORTUNE LIMITED has exported plastic conduit and wiring systems for 20 years, running 35 extrusion lines for trunking and conduit alongside 55 injection molding machines that produce every angle, tee, coupling and end cap. Profile and fitting come from one tooling programme, so covers clip flush and joint lines stay tight.

Production follows British Standard (BS) requirements, with regular shipments to Nigeria, Ghana, Saudi Arabia, the UAE, Malta and Thailand, and colour matched across the range so an ivory profile never arrives with a grey angle.

Count before ordering. Walk the route and mark every recessed corner, projecting corner, flat turn and branch, then add the couplings and end caps each run needs, plus about ten percent for breakage and late layout changes.
