Downspout Shoes (Rainwater Leaders)
Traffic may cause damage to light sheet metal rainwater leaders. Cast iron downspout shoes at lower levels provide protection. Table shows various standard types in straight, offset and angular shoes. Fastening lug slots are 5/8". R-4927 downspout adapters are used between the sheet metal downspout and the surface drainage pipe. Cast iron adapters are made to fit cast iron soil pipe; however, they can be fitted to PVC pipe with the use of a no-hub coupling (furnished by others).
Can be furnished with a powdercoat finish or with one coat of black primer if requested.
NF Trench Products meet and exceed the requirements in ASME A112.6.3.
Regulatory-compliant cast iron Detectable Warning Plates from Neenah Foundry offer appealing aesthetics, exceptional longevity and freedom from maintenance. By using Neenah's Detectable Warning Plates, specifiers can be confident that the critical warning message will be delivered for the lifetime of the installation.
The Adirondack collection is reminiscent of older traditional tree grate offerings and may be an excellent choice for a historical site. Contact us to help you with sizes or shapes - our Neenah sales staff is interested in your ideas.
If something a little different and very eye-catching is what you are after, consider the Greenwich collection. These tree grates have the narrow slot openings and the visual appeal that many architects now seek in their landscape designs. If you don't see the size you want, give us a call.
Neenah's tree grate frames are designed to make the installation job easy and accurate. Our frames can be incorporated into your forms in just minutes. The seat of the frame should be cleaned prior to setting the grate. Grate halves are to be bolted together on the underside using the bolt slots provided.
When planting trees in urban settings, one must provide enriched soil, proper drainage and a means of providing water and air to the roots for proper tree development.
Arborists encourage use of the largest tree pit possible, in response, Neenah offers our EXTENDED collection to meet this growing need.
Neenah Tree Grates can provide the means of getting the proper moisture and air to the roots for a healthy, long-lived specimen. No typical tree pit works for all situations. Urban designers must develop tree pits for each unique site. Soil scientists, arborists and urban foresters can provide valuable assistance when dealing with the following sub-surface conditions: aeration, drainage, irrigation and feeding, enriched soil, methods of flushing salts and/or avoiding their accumulation and methods of minimizing future soil compaction.
Trees are beautiful in daylight, yet in the darkness of the night they become shapeless and non-descript. Extend their natural beauty through the hours of darkness with tree grate illumination. Most Neenah Tree Grates can be made with removable light-opening sections so that sub-grade lighting units can be easily installed. All light-opening sections are secured with countersunk screws to prevent unauthorized removal.
Neenah Tree Guards are manufactured from hot rolled, pickled and oiled mild steel in the five standard illustrated styles. Guards are designed to be attached in four places to bolting lugs which are integrally cast to the underside of the tree grate.
Pressure Relief Valves
Adjusting rings (or extension rings, as they are sometimes called) eliminate the necessity of raising or replacing existing manhole frames on resurfacing projects. The cover recess is the same depth and diameter as the existing manhole frame. Amount of raise coincides with thickness of resurfacing material, thereby bringing the manhole lid to new position flush with refinished roadway surfaces.
Curb Sidewalk Guards
Heavy Duty Bases only furnished in cast iron. Special lettering available at additional cost. Cored hole for sign post is standard. Pipe tap is available if specified.
Groove supplied in standard three-foot maximum lengths, with slot dimensions as shown in table. Fractional sections may be obtained to give any overall length required.
To determine the number of plates needed, an arc length and a radius are needed. If the arc length is unknown, use the calculator to determine it by entering the radius and chord.
The American Recovery and Reinvestment Act (ARRA) of 2009 was enacted to stimulate the American economy by supporting American jobs. A "Buy American" provision in the Act mandates that "none of the funds ... made available by this Act may be used for a ... public building or public work unless all of the iron, steel, and manufactured goods used in the project are produced in the United States." Millions of Americans, such as those working at Neenah Foundry's seven manufacturing plants, rely upon this stimulus funding to protect their jobs and their families.
