The packing of the Durablock manometers…
The packing of the Durablock manometers is very poor. There is no padding on the bottom of the box and they are shipped Plexiglas facing down.

Easier than trying to get what I needed at Grainger. Complete selection was actually able to find a better product for my needs not stocked at Grainger. No Grainger markup.

The search function in the website is a little touchy. If you don't know exactly what the item you are looking for is called, it is going to be hard to get a good search return. On the other hand, if you have just the begging of the part # you get really helpful results.
