These Inter Dyne Systems Mod-Rack Stainless Steel Laboratory Pegboard Systems are constructed from 20-gauge, type 304 stainless steel with a polished finish. The easy-to-maintain material will not corrode, does not stain, and is autoclavable. An integral stainless steel drip trough with a drainage connector directs water back to the sink, preventing accidental drainage on the back of the pegboard.
