Description
KSS Closed Slotted Wiring Duct
KSS closed slotted duct provides organised cable routing inside switchboards, control panels, machinery and electrical enclosures.
The VDC series uses a closed-slot sidewall design with 8mm cable-entry openings. This provides more sidewall support than conventional open-finger duct while still allowing individual conductors to enter or exit the wiring channel where required.
Each standard length includes the PVC duct base and removable cover and is supplied in a 2 metre length.

These dimensions match the VDC product family published by KSS, including the 25×60, 40×40, 40×60, 40×80, 60×60, 60×80, 80×80 and 100×100mm models.
Closed Slot Design
The VDC series uses an 8mm closed slot with 10mm spacing.
Unlike fully open-finger wiring duct, the closed sections between each opening provide additional sidewall support. However, individual wires can still pass through the slots at the required position.
KSS also allows the slot openings to be cut where a larger cable exit is required.
Switchboard & Control Panel Applications
Closed slotted wiring duct suits applications including:
- Switchboards
- Control panels
- Motor control centres
- PLC cabinets
- Electrical enclosures
- Industrial automation
- Machinery
- OEM equipment
- Instrumentation panels
- Power distribution equipment
The removable lid keeps wiring contained while still allowing access for installation, inspection and future modifications.
