This kind of spacers are used as a multichannel and multilevel system for all
kinds of underground cable duct systems; especially recommended in
various underground cabling applications and underground cable duck bank systems
. They are especially designed
with interlocking devices to also make an assembly of duct bank
trenches stable. Pipe spacers have base and intermediate parts that
connect horizontally and vertically to provide for as many ducts
needed. They are designed for 4” (110mm.) and 6” (160mm.) PVC pipes.
