ATMI 233430599 180 Degree Load Lock Cover 233430598 This unit was represented to us as being manufacturer refurbished, but we can not verify that. This unit has two different labels on the bag with both part numbers: 233430599 and 233430598. The bag has hand written on it, "this package is 180". It does look like another unit that we have that is a 180 degree model, but we are not experts on these items and we did not open the bag. Please check the pictures carefully. The bag is taped shut rather than sealed, possibly because it was found to be labeled wrong. It only comes with what is shown in the pictures. WF C8-8 d 8524198 rl fdk 80815238
