Installation Procedure
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.
Planting and Lighting
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.
Lighting
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.
Custom Logos
Does your company have a corporate insignia or municipal logo that you would like to incorporate into your architectural designs or construction project? Neenah Foundry has the ability to take your concepts and recreate them through Sidewalk Medallions, Tree Grate Logos and Custom Manhole Covers. This is a great opportunity to tie together a common municipal or corporate theme.
Tree Guards
Most tree grate units are furnished standard with four inconspicuous guard lugs on the underside to facilitate attachment of tree guards.
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.

Manhole Frames & Covers
If you happen to glance down as you're crossing the street in your neighborhood or town, it's likely you'll step across a Neenah Foundry manhole cover. There are literally millions of our flagship products in towns all across the country. We manufacture cast iron manhole frames and covers in a variety of sizes, shapes and cover designs. Our pattern shop can even create a custom "logo lid" for your city or neighborhood.
Camlift Manhole Covers
Neenah Foundry now brings you the next generation in manhole covers, the Camlift. This means no more dead lifting covers that are too heavy, and helps reduced the time lost to job injuries. Camlift utilizes ductile iron to meet the load bearing capabilities required for airport and port conditions.
|
Perforated Lids
These perforated lids are ideal for areas with restricted water flow. The light-duty lids will vent the area and are best used in a low-volume application.
Liftmate Hinge System
The patent-pending LiftMate™ Hinge System eases operation and access while virtually eliminating many of the traditional hazards of working with manhole and grate covers. The LiftMate Hinge System uses a controlled motion pivot to help protect against excess strain and on-the-job injuries.
Manhole Adjusting Rings
For raising manhole covers when pavement is resurfaced.
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.

Vane Drain
Neenah's Cast Iron Slotted Vane Drain offers ease of installation along with the superior vaned configuration to capture previously unexpected quantities of water when placed perpendicular to the flow. Installation is accomplished by sawing a slot in the top of conventional PVC pipe, placing the pipe on grade, installing the Cast Iron Slotted Vane Drain in place and pouring the concrete. When used in conjunction with a vane grate inlet, virtually all of the water in the street, which would normally bypass the catch basin, can be captured. This permits the spacing between inlets to be increased. An additional benefit is the added safety factor obtained should the catch basin be plugged or covered with snow. The unit may also be installed wherever sheet flow capture is required.

Buy American
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.
