Piper PA-18 3/8 Piper U Channel - 6 Ft

Part# 05-04564
MFR Model# U750-285


Mild Steel


The U channel came for the second time today. The shipping tube was broken again. The U channel is salvageable for the sections I need. I am disappointed in the shipper (UPS), twice the material was damaged with no blame to Aircraft Spruce. Im not sure what the fix is, but UPS is dropping the ball , my opinion.

One of the three pieces was found bent. It was packed well , so I assume it was bent before packaging. Luckily it was still suitable for my needs.
