MVG's Extra Heavy Duty walkway RF absorber is composed of a composite sandwich panel shell over a
standard AEP type material. The AEWW-EHD offers excellent load bearing and wear characteristics. Its
light weight but durable, rigid surface is impact resilient and ideal for rolling equipment into chambers.
The material’s ability to withstand higher loads than most walkway materials is due to the construction
technique. Custom sizes and shapes can be provided. The walkway absorber is taller than standard
absorbers. We generally recommend using walkways one size smaller than surrounding absorbers.
