Catalog Number	Lamps	Length	Function
CD12-1121	1-2 Foot	21"	Modular Unit
CD12-1133	1-3 Foot	33"	Modular Unit
CD12-1145	1-4 Foot	45"	Modular Unit

CD12-11T	1-4 Foot	27"–48"	Telescoping Unit
CD12-1C	—	12"	90° Universal Corner

*Each run MUST include a Telescoping fixture as the CD12 end plates only ship as part of the Telescoping fixture.

Ordering Instructions

Continuous Rows:

1.Determine run length.

2.Determine lamp configuration (1 or 2 lamp).

3.Use Ordering Information Chart to find catalog numbers.

A.Each run ends with a TELESCOPING UNIT.

B.Starting with the longest MODULAR UNIT, fill in the remaining run.

Square/Rectangle Patterns:

1.Consult plans and mark locations of corners.

2.Calculate net footage of each linear run.

3.Deduct 12" for each corner.

4.Determine catalog numbers the same way as a STRAIGHT RUN.
