This new series of ducts is used to retain and protect wires installed in an enclosed area or space. The duct's retention feature ensures that wires remain in slots when its cover is removed, while ducts with open slots permit wires to be inserted or removed with terminations attached. Both quick release/lock covers and non-slip interlocking covers are availaable. All models are constructed of high impact, rigid PVC material. Unslotted and standard and thin slotted models are available in both series. And the Interlocking Cover Series features snap-off sidewall fingers to accommodate wire bundles without cutting tools. Sizes range from 0.59 x 0.59 in. to 5.91 x 3.94 in., depending on series.
