STEP 6
SPRING ATTACHMENT
Rotate curtain assembly so that the bottom bar is at the top
of the curtain roll. While holding the door from rotating,
carefully stretch the spring end to the bracket to determine
the bracket hole nearest to the loop in the spring end.
Position the 5/16-18 x 1” hex head bolt and flat washer in
the spring loop and stretch the spring to insert the bolt into
the previously determined bracket hole. Loosely install the
lock washer and nut on the outside of the bracket to hold the
spring stretch. Rotate the spring until it is centered on the
bracket, with all bracket tabs inside the spring, and securely
tighten the spring attachment bolt.
See step #13 for Tension-Pro bracket spring attachment.
If installation permits, use vise grips to secure spring loop to bracket for a
stretch free method of installing the spring attachment bolt.
STEP 7
PRE-TENSION THE DOOR SPRING
Starting with the bottom bar angle at the top of the curtain roll, apply two
complete turns of pre-tension to the spring by rotating the curtain roll in the
direction shown. Depending on door size, it may be necessary to pry the
bottom bar past the guide flare. The amount of tension required may vary
slightly. Final adjustment, if necessary, will be made in Step #9.
Spring tension can cause curtain roll to rotate rapidly.
Securely hold curtain roll from rotating while applying
pretension or serious injury or death could result.
Securely hold door curtain until bottom bar stop fasteners
have been tightened. If not securely held, door may raise or
drop, possibly causing serious injury or death.
Cut the tape that holds the door in a roll and gently pull the curtain down into the guides on both sides until the
bottom bar is below the bottom bar stops. Do not pry on the bottom bar stops to get bottom bar past, loosen fasteners
until bottom bar angle easily clears stops. If the door has a tendency to close, secure in position using clamps. If the
door has a tendency to rise, secure in position using a wood prop.
While the door is secured from moving, tighten the bottom bar stop fasteners on both guide assemblies.
