Combi Ducting Sourced from Europe, our Black Combination Ducting is strong and reliable with a robust and hard wearing outer casing. Purposely designed in black to prevent light reflection through the ducting, it has a double layered construction with an aluminium inner and a plastic outer, greatly increasing its resistance to tearing while also preventing light leaks. Dual layered construction – aluminium sheath with polyester outer Greater resistance to tearing than standard aluminium ducting Reduced noise levels compared with single layered ducting Shipped in a retail box Prevents light leaks Available in 5 and 10 metre lengths, from 4 to 12 inches
