The Scepter App consists of two PVC calculators for electricians and electrical engineers. The first is an Expansion and Contraction calculator which allows you to calculate the number of expansion joints required due to expansion and contraction of the conduit. The second is a Support Spacing calculator that helps calculate the number of supporting spacers required for runs of PVC conduit. App users can also explore the IPEX electrical products range and find detailed information about the products.
