Cable Tray Length Planner
Turn a route length into a practical tray section schedule, joint count and connector quantity without hiding the final partial section.

Why the section plan is not just route ÷ stock length
The purchasing quantity must be a whole number of sections. This tool also exposes the nominal remainder, helping you distinguish unavoidable stock overage from a hidden “waste” factor.
Sections = ceiling(planning route ÷ stock section length)
Joints = max(sections − 1, 0)
Connector sets = joints × connector sets per joint
Worked example
A 96 m route with 3 m tray sections requires 32 straight sections before allowance. With a 5% planning allowance, the route becomes 100.8 m and the procurement quantity rises to 34 sections.
Why the last section matters
A whole-section result does not mean every section is consumed in full. The physical final section can be cut to the remaining route requirement, leaving a potential usable offcut.
Frequently Asked Questions
Are connectors counted automatically?
Yes, using the connector-set count you enter for each joint.
Can the allowance be zero?
Yes, which is useful when the route is already a measured fabrication schedule.
