"Pinch" is a bit of an inaccurate description. The drawings do not come in
direct contact with anything other than a rigid 100#stock red rope type
material folder/pouch.
The folders are held in place by a 'compression' system, consisting of flat
bands of metal and large 3-4" diameter springs assemblies, suspended by
steel rods that roll on nylon wheels on a framework.
The cabinets are insulated and water and fire resistant and offer six sided
protection. When closed (and locked), if the room they are in is not
fitted with floor drains, the only risk they have of water exposure is if
the water becomes so deep and the files are not filled, they MAY become
buoyant and tip over, and if left for hours, water could breach the seal on
the top edge.
The only question regarding "Archival" is if the folders are acid free or
not, and I honestly don't know the answer to this... and I don't know if
someone like Hollinger makes folders as large as these, suited for use in
these cabinets.
