PVC bends were part of shaping the wiring route around the roof rack. I fitted elbows beside junction boxes as I joined the straight pipe runs together.
The roof route could not be made from straight pieces alone. Boxes, rack positions and the direction of the next run all influenced the bends.
The ANPTGHT three-quarter-inch 45-degree fittings were included in my materials for the route. My photos show angled PVC connections alongside the metal boxes.
Turning the Route Beside the Junction Boxes
I connected a PVC elbow at the driver-front box section.
I fitted the adjoining pipe and mounted the assembly along the extrusion.
I continued pulling wires and joining the remaining route sections around the rack.

My Takeaway from This Job
A box location also determined where the adjoining pipe needed to turn. The close photograph shows the box, bend and straight run together, which makes the difference between an angled elbow and a sweeping bend easier to compare.
Each box position helped determine the direction of the next pipe section.

Socket ends for pipe sections
An elbow changes the direction of a PVC assembly, so a cut list needs to allow for the pipe entering each socket. Measuring only the exposed straight length can produce a different overall frame size. For a van routing mock-up or removable frame, lay the elbows and pipe sections out together before fixing the final dimensions. Keep the exact fitting size with the pipe record. These are the purchased ANPTGHT elbows, separate from the other conduit and junction-box parts in my diary.
Why Measure The Assembly With The Elbows In Place?
The pipe enters the fitting sockets. Overall size therefore depends on both the exposed pipe and its position inside each fitting.

Two Alternatives to Compare
The Rainbow Dream fitting is another 45-degree socket elbow. The Carlon option takes a different routing approach: a sweeping 90-degree conduit bend with a belled end. These are two geometry choices for laying out a turn, with different angles and space requirements.
