of risers fit in 24"x23"x9" box

The Sim/Tech 24” diameter x 8” tall modular riser stands up to back filling and more.  And because it is sold in three segments that are assembled when needed it only takes up a quarter of the storage space of a comparable sized riser.  It has 9 flat surfaces and 51 drillable dimples for access and options.  It can be cut down to 2” or 4” heights and is stackable to virtually any height.  It can be easily precast into concrete tanks or used with an adapter ring to install onto an existing tank.  They are also perfect for use as distribution centers, meter pits and containment rings. 

The picture on the left shows a visual comparison of the space saving attributes of the Sim/Tech Riser.  A case of Sim Tech risers (24”x23”x9”) holds enough riser segments to build a 24” diameter riser that is 32” tall.  Now a large riser can easily fit in a truck for transportation, even in the cab.
