Pulley System Adjustment
The tension on the cable that provides constant force during cable extension and retraction
is maintained by proper adjustment of the pulley system. Too little tension and the cable will
have slack or may slip out of the pulley tracks, and will not retract properly.
To Adjust the Pulley System:
1. Before beginning pulley system adjustments, ensure the cable routing around the pulley
system is correct (see below) and the cable is completely retracted into the enclosure.
Cables should be in the correct
pulley track, taught, and parallel
to each other.

ATTENTION:
• Each Extron retractor model is designed with custom-made cable and a unique matching spring that work
together to maintain cable signal integrity and preserve consistent cable retraction pull force over the life of
the product. Alterations to the retractor will cause premature failure of the retractor system and cables.
• Modifications to the Retractor System are prohibited and will void the Extron warranty for this product.
