I am looking to purchase prep trays for wiring harnesses. We are bulding harnesses that need as many as 50 unique tray locations. If anybody has any suggestions or a product please let me know. I am looking to set up 6 stations.

Hi Chris,

The ones I saw were for helicopters and were home made from 4'x8' sheets of 1" plywood. They were stored and used almost vertically (Say 10 degrees tilted back from vertical.) (4' side vertical) and could be tandemized (end to end) for longer runs. Each wire along the main bundle was fanned out (upwards or downwards) via nylon covered steel pegs, each about 1/2" in diameter, to it's proper termination length and position. It was also identified by name and color on the board itself. (At the end point.) After identifying, terminating and testing each wire, the harness was gently and carefully bound with a narrow (1/2"), flat, polymeric tape (Via slots along and through the board behind the main bundle.) and then removed from the wire tray and helically wrapped with tape.

It seemed to work really well for small machines. Obviously this is of little value for most harnesses in big machines such as a 767.

Kindest regards,
