Seismic, Penetrating and Non-Penetrating Roof Supports for Piping/Ductwork
Roller Supports
MAPA Products
Available for piping up to 10"
MAPA Products offers the most diverse line of supports for roof top applications. These range from free standing, non-penetrating to structurally attached supports systems for seismic and high wind applications.
Typically used as a pipe support stand for natural gas piping installed on single ply and built-up roofs; the rubber pipe roller cradles the piping, while protecting the roof membrane and allowing it the freedom of movement necessary due to thermal expansion. The adjustable rod assembly allows piping to be installed level on tapered roofs.
Seismic Rooftop Pipe Support
MAPA Products
Available for piping up to 6"
Structurally Attached Single Post Supports provides a secure weatherproof penetration of the roof deck by which a variety of support and restraint options become available. The MX-1-SA series is a stainless steel structural single post support with a standard 4" riser with 4" diameter base and a 10" X 10" flange with rounded corners. It is available with a 6" riser and SS pipe clamp to be used as a structural condensate support. This will provide 12" clearance from roof surface.
Curb Support
MAPA Products
The MAPA Curb Support Series provides a manufactured curb support designed as a cost-effective heavy-duty platform upon which to mount or secure equipment and piping systems. These structurally attached supports allows for fewer disturbances to the roof membrane by minimizing the overall flashed area of the installation.
Rooftop Pedestal Hydrant
MAPA Products
The MPH-24D:24/9 utilizes a 1" bronze valve within a fully insulated stainless steel shroud. This Auto-Drain assembly utilizes a full port ball valve with an auto-drain port that is located below freeze line at the base of the Hydrant. The "drain down design" of the MPH-24D:24/9 hydrant allows the water remaining in the stand pipe to discharge through the field provided drain down piping to an open site drain located below the roofline.
An auto-drain type hose vacuum breaker is permanently attached to the discharge outlet located near the top of the pedestal. Supply connection is made at the 3/4" fitting located at the base of the hydrant.
Rooftop Pedestal Disconnect
MAPA Products
The MAPA Products Fusible Rainproof Pedestal Mounted Safety Switch provides local disconnect of the electrical service at roof mounted equipment. Disconnects are available in General Duty or Heavy Duty Series. The stainless Shroud with integrally welded deck flange enables a positive weather-tight flash of the unit to the roof membrane without the need for additional flashing or pitch-pan. The need to interrupt electrical service remotely in the case of equipment change-out can be avoided since service disconnect is mounted adjacent to rather than onto the equipment.
The standard Stainless Steel Shroud extends above the roof line thirty-six inches with an additional twelve inches beneath roofline so as to permit the unit to be securely fastened to the roof structural members by securing the under-deck mounting flange to a welded deck flange. The roof flange is provided with fastening hardware to enable the installer to secure the flange first against the shroud and then onto a deck flange.
