The purpose of this kit is to help the aircraft homebuilder make their own heat shields. Experience has shown that a heat shield is rarely over 8 inches, thus the 20 inches of shield material in the kit should provide the various lengths needed. You would not be limited to heat shields that are fixed in length. Also you can position the brackets in many configurations allowing the shield to be attached to the exhaust pipe without interference with bends, other clamps, probes, and so forth. You do not have to limit the location based on standard heat shield attachment configuration.
With the 20 inches of shield material and ten brackets, you will have many combinations of lengths and configurations. You do not have to use all of the shield material provided.

• 20 inches of preformed aluminum heat shield.
• 10 predrilled and formed stainless steel brackets
• 25 AN470AD-4 rivets
