NOTE:

 Refer to Package Contents / Breakdown of Parts, to determine which Center 

Bracket(s) came with your door.

NOTE:

 Refer to Package Contents / Breakdown of Parts, to determine if your door came with 

a coupler assembly.

IMPORTANT: 

THE SPRING WARNING TAG(S) SUPPLIED MUST BE SECURELY ATTACHED 

TO THE STATIONARY SPRING CONE(S) IN PLAIN VIEW. SHOULD A REPLACEMENT SPRING 

WARNING TAG BE REQUIRED, CONTACT WAYNE DALTON FOR FREE REPLACEMENTS.

NOTE:

 Measure the diameter of your springs. If your spring diameter is 3-3/4”, the springs 

do not share center brackets. If your spring diameter is either 2” or 2-5/8”, then two springs 

will share the same center bracket, unless a coupler assembly is provided.

IF YOU DON’T HAVE A COUPLER ASSEMBLY:

 Slide center bracket bearing into the spring. 

Align the stationary spring cone(s) with the holes in the center bracket. Secure the torsion 

spring(s) to the center bracket with (2) 3/8” - 16 x 1-1/2” hex head bolts and (2) 3/8” - 16 

nuts.

IMPORTANT: 

NEVER USE MORE THAN ONE BEARING WHEN ATTACHING TWO SPRINGS TO 

ONE CENTER BRACKET.

IF YOU HAVE A COUPLER ASSEMBLY:

 Slide center bracket bearing into the spring. Align 

the stationary spring cone with the holes in the center bracket. Secure the torsion spring to 

the center bracket with (2) 3/8” - 16 x 1-1/2” hex head bolts and (2) 3/8” - 16 nuts. Repeat 

the same process for the other center bearing bracket.
At the middle of the two center bearing brackets, re-assemble the coupler assembly by 

loosely fastening the coupler halves together using the (3) 3/8” - 16 x 1-1/2” hex head 

screws, (6) 3/8” washers, (3) 3/8” lock washers and the (3) 3/8” - 16 hex nuts, previously 

removed.

NOTE:

 Ensure both torsion keyed shafts have equal amounts of the shafts extending from 

each end bearing bracket.

 Always assemble the left hand cable and cable drum first to help maintain equal cable 

tension on both sides of the door.
Hook the counterbalance lift cable into the left hand cable drum. Slide the left hand cable 

drum up against the left hand end bearing bracket. Counterbalance lift cable should 

terminate at the 3 o’clock position. Tighten the (2) set screws in the drum to 14-15 ft. lbs. of
