System uses modular elements. The spacer elements are modular and interlock at the sides and top to secure the ducts against separation during backfiling. Two modules are offered: a base spacer-flat at the bottom and an intermediate spacer. When the duct bank is capped with a spacer or a Cap-Lok (see accessories), the need for spacers as top caps is not necessary. The Cap-Lok is an easy and cost effective method for securing the top of the duct bank.
Assembly is a snap. Base and intermediate spacers interlock both vertically and horizontally; the interlocks plus wide base-plates provide solid support for duct bank.
Push together. As shown above, the suggested method is to snap spacers together with a vertical push..
Slide together. As shown at right, above, units will also slide together; this method is for use in unusual field conditions such as duct repair.
