The HBI-8516 Orange 8" Hickenbottom Extension is an underground riser extension section designed to connect from the tee and extend up to the inlet for proper height and fit. This 8" orange, holed section features 5/16" perforations and can be cut at marked locations to fine-tune inlet height. The top of the riser has already been removed, so it’s ready to connect directly to the bottom spigot of an inlet.
