After our Discussion on Skype today and the latest delivery, it seems clear to me that your packaging company /and or transport from ship to PSG is responsible for the damages we have on MSM Guarding.
Such as : bended doors and hinges, sometimes Plexiglas is not correctly fixed, damages on lacquering etc..
Please show those pics, this happens when the top mounted guarding gets tightened down. I hope they help you to train the supplier.
The packaging must be improved to avoid these issues.
