Ordering Instructions
Individual Fixtures:
1. Order number of FIXTURES.
2. Order one END PLATE SET per fixture.
Continuous Rows:
1. Determine run length.
2. Use chart above to find catalog numbers. Each run ends with a telescoping unit.
3. Order END PLATE SET for each open run.
Square/Rectangle Patterns:
1. Consult plans and mark locations for corners.
2. Calculate net footage of each run.
3. Deduct corner dimension from each corner.
4. Determine catalog numbers the same way as a straight run.
