The Density Base Plate provides a stable base for the Sand Cone. A center flanged 6 ½ in (16.5 cm) diameter hole receives the standard Sand Cone Funnel (S-120).
The center hole may also be used as a template to gauge the diameter of the test hole. The flanged Density Base Plate also helps in preventing loss of soil removed from the test hole. It is made from cast aluminum alloy.
