Frequently asked questions about the Cable channels category
Cable channels — what are they and what are they used for?
Cable channels are plastic or metal ducts and trunking systems for neat, protected routing of electrical wires and cables in residential, commercial and industrial buildings. They prevent tangling and mechanical damage, simplify maintenance and provide an aesthetic solution for cable installation.
What sizes of cable channels are available and how to choose by dimensions?
Typical sizes in the range include 15x30 mm, 25x25 mm, 40x60 mm and 60x90 mm. Choose a channel with internal cross-section about 20–30% larger than the combined cable diameter to allow easy routing and ventilation.
What colours and finishes are offered (e.g. RAL9010, RAL9005, bronze)?
Available finishes include white RAL9010, black RAL9005 and decorative bronze (pronks) options. Choose white for blending into walls, black or bronze for contrasting or visible installations.
What is the difference between KARBIK LFG 25x25 and 40x60 models?
KARBIK LFG 25x25 is a compact 25×25 mm trunking for small cable runs; 40x60 is a deeper 40×60 mm profile for larger cable bundles and electrical components. Use 25x25 for sockets and low-voltage wiring, 40x60 for power cables or multiple cables.
What accessories come with cable channels — corners, end caps, covers?
The range includes accessories such as external and internal corners, end caps (OTSAKAAS) and covers. Product names show items like VÄLISNURK, SISENURK and OTSAKAAS sold in packs of 2–4 pcs.
Which brands of cable channels are offered and how do they differ?
Brands include Legrand, Schneider Electric, DKC, OBO Bettermann and EAE. Differences lie in materials, dimensional tolerances and industrial certifications; Legrand and Schneider commonly offer modular systems and extensive accessory ranges.
Can cable channels be used for both low-voltage and power cables together?
Yes, but it's recommended to separate power and low-voltage circuits into different channels or use trunking with partitions to avoid interference. If sharing one channel, ensure correct sizing and leave air gaps according to regulations.
What pack sizes do accessories come in — 2 or 4 pieces?
Accessories are sold in packs of 2 or 4 pieces for certain items. Product names like VÄLISNURK RAL9010/2TK and OTSAKAAS RAL9010/4TK indicate 2-piece and 4-piece packs respectively.
Are KARBIKU cable channels suitable for concealed installation in wall or ceiling?
KARBIKU LFG channels are intended for surface-mounted installation on walls or ceilings to provide neat routing. For concealed installations use built-in trunking or chase solutions — KARBIKU items are surface-mounted products.
