Less than 900 pair = 5" (127 mm)
900–1800 pair = 5–7" (127–178 mm)

the cathedral windows facing the color code guide.
Push the “L” clip knob in to seat the index strip
into the channel and locate it under the “L” clips.
Select a “through” group to be half-tapped. Wrap

the connector.
Use the error tester tool to check for
correct conductor placement.
