KCC Manufacturing
KCC Manufacturing offers prefabricated cricket diverters for large and unusual field conditions. They can be installed around penthouses, elevator shafts and process equipment that protrude through roofs. The factory-fabricated cricket diverters are produced in aluminum, Galvalume and stainless steel, and are designed to maintain the integrity of roof systems.
Plyco Corp.
Plyco’s MW100-25 low-profile ridge vent has an open top for air flow and an internal diverter to direct water to the side and onto roofs. It is 3 inches above roof peaks. The 14 1/2-inch-wide, 10-foot-long vent has a 2 3/4-inch throat with a flange.
RCS – Roof Curb Systems
RCS – Roof Curb Systems offers square-to-round covers to transition round pipe stacks penetrating through roof curbs. For pipe stacks 40 inches or less, curb outer dimensions are 9 inches larger than pipe diameters. Cover openings are 3 inches larger than pipes to allow for 1 1/2 inches of thermal movement.
RHEINZINK America Inc.
RHEINZINK offers fabricated zinc gutter systems in half-round and box shapes. Half-round gutters come in 5-inch, 6-inch and 7 1/2-inch diameters. Lengths are produced 9.84 feet to 19.68 feet. Zinc gutters are produced in 0.7-mm and 0.8-mm thicknesses. Materials include prePATINA blue-gray, graphite-gray and CLASSIC bright-rolled. More than 300 parts and accessories are available.
Ventco Inc.
Ventco’s ProfileVent is a single-layer ridge vent for metal roofs. It is modified polyester, non-woven, non-wicking, fiber-based matting. It prevents compressing the ridge vent material, which reduces the free area after installation. During installation, glue spots prevent slipping. ProfileVent comes in rolls of 20 feet, 50 feet and 100 feet.
The BILCO Co.
BILCO’s smoke vents’ standard features include a Thermolatch II positive hold/release mechanism that ensures reliable vent operation in the event of a fire, and a curb-mounted fusible link that allows a latch to be quickly reset from the roof level. The double-leaf smoke vents also have gas spring operators to open covers in snow and wind.
