REMOVABLE XPORT SPIGOT INSERTS

This system provides a two-piece PRO-ECO-LITE - XPORT tm headwall.

* The main XPORTtm headwall piece is inventoried in the various headwall sizes.

* The second piece XPORT tm insert is a disc that fits into the XPORT tm headwall.

* The XPORT tm insert disc comes with a variety of spigot pipe types and sizes in both
ENVIRO-CONNECT tm and the standard FRP Spigot.

* The insert can be rotated 180 degrees thereby changing inert location.

* The invert location for all the potential pipe sizes is the same. .

* The XPORT tm disc can only be installed 2 ways 180 degrees to each other. This feature
provides two potentially different invert locations, which is also an added benefit for retrofit
projects where all the parameters are not known.

* The XPORTtm headwall and insert are matched series for series, i.e. a 3 Series insert disc
will only fit into a 3 Series headwall. Yet a 3 Series insert disc may come in various FRP
spigot sizes or ENVIRO-CONNECTtm spigot sizes.

* This XPORTtm system permits instant supply of headwalls in a multitude of pipe types and
sizes at a much lower cost of inventory. The XPORT tm system also accommodates last
minute site changes or flexibility in meeting retrofit project needs.

* This XPORTtm system allows the supplier to be able to offer an immediate delivery from
stock of multi-diameter options in pipe size. FRP spigot or pipe specific sections are factory
bonded to a bolt on disc (XP spigot). The interchangeable disc (XP spigot) permits supply of
all the variations in pipe size or type to be added to any stock XPORTtm headwall and
delivered immediately to the customer
