The CMAB aluminum standard curb spring cap has been largely superceded by the RSC design. This complete rooftop spring curb is supplied in standard deflections up to 3” and as much as 5” in special designs. Springs are adjustable and removable.

While most RSC curbs are standard heights for flat roofs, we customize to any height and compensate for roof pitch as well.
