Historically the component approach of standard sheet metal shop curb companies has been to let the customer be responsible for determining the correct curb size by filling out an order form. This approach transfers responsibility to the builder or customer and the standard curb company is released from all responsibility. Curb support is left to the erector or contractor and accessories may or may not be included with the curbs and installation details are left to others. This kind of components approach tends to create problems. At RCS, we prefer to create solutions for our customers.
