ATTENTION:

 These instructions describe the installation of the optional 

ridge vent kit. (Additional purchase required.) The ridge vent kit is 

designed for use with the 

HF

 model (5.2 oz. cover) only. If you have the 

C model or did not purchase the ridge vent kit, skip those installation 

procedures when presented and continue as instructed.

Do not cut the film of the 

HC

 model to install ridge vent kit.

CUSTOMER-SUPPLIED END FRAME: 

Construct the end frame for the 

roll-up end panel using 4" x 4" wood posts. The doorframe materials are 

supplied by the customer. If quality 4" x 4" lumber at the lengths needed 

is not available, construct 2-ply wood beams using 2" x 6" boards secured 

together with exterior grade bolts and nuts. Center the doorframe in the 

end wall and dig the holes for the doorjambs. 

Stagger all joints. Do not align.

 

Use treated lumber and set in 

concrete for best results.
