OPTIONAL MAIN COVER INSTALLATION W/ ROLL-UP 

SIDES (CONTINUED)

Photos show installing the spring into the U-channel on 

the outside of a frame. The process is the same for the 

U-channel attached to the top of the end rafters.

5.  Continue adding the spring into the U-channel at the 

top of the first end rafter. Ensure that an even amount 

of the cover is exposed and maintained along the edge 

of the frame as it is attached. 

NOTE:

 The cover material is cut longer/wider than is 

required to cover the frame. For easier anchoring, allow 

approximately 10" to extend past the edge of the end 

rafter as the cover is anchored in place.

6.  Continue down both edges of the first end rafter 

until the entire length of the end of the main cover is 

secured in place.

7.  Stretch the cover to the other end of the building and 

repeat the steps to secure the main cover in the U-

channel. 

NOTE:

 Pull the cover tight as the spring is inserted into 

the U-channel.

8.  After the cover is stretched end-to-end and secured 

using the spring and U-channel, move to one side of 

the frame and repeat the steps to anchor the main 

cover to the first side.  

Begin at one end of the U-channel and work toward the 

other. It is also possible to begin at the middle of each 

side and work toward each end. 

NOTE:

 Maintain an even length along the side. The 

final stretching of the cover takes place when the last 

side is secured.

9.  After securing the first side, move to the remaining side 

and secure it in place. 

IMPORTANT:

DO NOT REMOVE TOO MUCH OF THE 

EXCESS COVER MATERIAL AT EACH END.

 Some 

excess main cover material–the material that extends 

beyond the end rafters–should remain in place. If the 

main cover needs stretched in the future, remove the 

spring from the U-channel, grasp the excess material, 

pull the cover tight, and reinstall the spring. 

The excess material along the sides is rolled up in the 

roll-up side assembly.

10. Once the main cover is installed and secured in the  

U-channel, follow the instructions provided with the 

Twist-of-the-Wrist Assembly if used.

11.  Once you have completed the Twist-of-the-Wrist 

installation and install your Anti-Billow ropes, read the 

Care and Maintenance

 section that follows.
