Double Hook Valley with Center Rib

This is a completed double hook valley with a center rib detail. The following illustrations and steps will describe how to form this detail on a brake.

 

Step 1 :

Place the roofing material on the brake with the colored side facing up. Bend the apron up 145° and release. Then open the clamp and slide the bend under and squeeze. Be sure to leave a gap for the cleat.

 

 

Step 2 :

This process should be repeated on the other side of the panel. Flip it around but leave the colored side up. Bend and squeeze this side as well.

The panel should now look like the image to the right.


 

Step 3 :

Remove the material and flip it over so that the hooks are facing down. Insert into the brake leaving 3" out from under the clamp. Bend up 105°.

 

 

Step 4 :

Flip the material again and place in brake leaving 1.5" between the previous bend and the nose of the clamp. Bend 145° and release.

 

 

 

Step 5 :

Lift the clamp and insert a shim as shown in the illustration. Clamp down to flatten the end.

 

 

Step 6 :

This step is the same as step 3 but on the other end. Remove the material and flip it over. Insert the other end into the brake leaving 3" out from under the clamp. Bend up 105°.

 

 

Step 7 :

Just as in step 4 flip the material again and place in brake leaving 1.5" between the previous bend and the nose of the clamp. Bend 145° and release.

 

 

Step 8 :

Lift the clamp and insert a shim as shown in the illustration. Clamp down to flatten the end.

 

 

Step 9 :

Pull the material out so that nose of the clamp is over the center and then pull out 1" more. Bend apron up 75°.

 

 

Step 10 :

Remove the material and flip it over. Insert so that there is 1" between the previous bend and the nose of the clamp. Bend up 90° and release.

 

 

Step 11 :

Flip one final time. Insert the material so that there is 1" between the previous bend and the nose of the clamp. Bend the apron up 75° to complete this bend.

Your detail should now look like the picture on the right.
