Zerust Plastabs® are thin, light, rigid polyethylene squares that are made with patented Zerust corrosion-inhibiting technology.

Their small, thin shape makes Plastabs® perfect for protecting critical surfaces within narrow or hard-to-reach areas from rust. They’re perfect for restricted spaces that contain compact electrical components, enclosure cabinets, and control boxes.

Zerust rated to protect a radius of 6" for up to two years. 

We like these for ammo cans.  One or two in each can is cheap insurance.  We recommend that you use them in conjunction with a humidity control device such as our 40g desiccant pack.

Price is for ten (10) Plastabs®.
