Installation Guide

Slide the spring(s), drums, winding unit(s) and end
bearing support (if supplied) onto the torsion tube
as shown in Fig. 5 and Fig. 6. Alignment may be
required before the tube will pass through spring
spacer inside the spring.
If you have one spring, see Fig. 5 for the
conguration of the components on the torsion
tube. The spring with “LEFT” stenciled on it and
green components MUST be put on the left side
of the tube. Make sure the end bearing support is
oriented so that the bearing is facing toward the
right drum.
Reminder: All references to left and right are
made assuming that you are inside the garage
looking out.
If you have two springs, see Fig. 6 for the
conguration of the components on the torsion
tube. The spring with “LEFT” stenciled on it and
green components MUST be put on the left side
of the tube and the spring with “RIGHT” stenciled
on it and orange components MUST be put on the
right side of the tube. The torsion tube coupler will
be located between the two springs if so equipped.
The drums should be oriented so that the slots are
facing away from the winding unit(s) and the end
bearing support (if supplied) as shown in Fig. 7,
views A and B. The drums are designated as
left side and right side by the letters “L” and “R”,
respectively, found near the cable slot.
NOTE: Verify that the drum marked with the
letter “L” is on the left side (Fig. 7, view A) and
the drum marked with the letter “R” is on the
right side (Fig. 7, view B).
NOTE: Springs may be different sizes
depending on the weight of the door.
