Vertical-Lok Spacers

SKU: N/A Category:


Vertical-Lok spacers stabilize duct banks, prevent distortion of bottom tiers and allow pre-assembly outside the trench.

The Vertical-Lok spacer system provides positive vertical and horizontal spacing of underground ducts while providing independent support for each duct in a bank. It’s the fast, easy way to build completely enclosed and locked-in banks of any size, with any number of tiers and any number of ducts side by side, in straight or curved runs.

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.
