Duraguard Frame Part No. DG0700PE  
Utilizing a high density polyethylene composite, this frame reinforces the channel edge to dramatically improve load performance and impact resistance.  It is extremely resistant to environmental exposure and many corrosive chemicals.  The anchoring flanges on the outer edge permanently and mechanically engage the frame into the concrete.  The cross bars eliminate sidewall deflection of the channel during concrete placement and ensure proper clearance for the installation of the grate every time without extra effort.  It is ideal for many markets including transportation, utilities, agriculture, food processing, public/government housing, industry, manufacturing, and recreational and chemical plants. Dimensions: 24"
