Our patented Pop-Lock process of two equal parts snapped together is a savings to our customers on freight, storage, and delivery to the job site. The MB-7 still retains the advantages of the 18" round boxes: Tapers to Bottom, Wall Thickness is approximately 1/2", Easy to Handle, R-4 Insulating Factor, Easy to Read Meter, Easy to Adjust to Grade. The MB-7 is primarily used for larger meter sets and moderately deep frost lines. For extra reinforcement the tongue and groove pop lock area can be riveted by either us before shipment or the customer after shipping.

Proven Processing
Our structural foam molding process allows our parts to have a cellular foamed core surrounded by integral skins. The process gives our products high strength-to-weight ratio making it have greater rigidity than solid parts of the same material and of equal weight.
