Manufactured from High Density Polyethylene (HDPE) and manufactured to BS EN 61386-24:2010, Twinwall ducting has a smooth internal bore, and a corrugated external wall providing excellent impact resistance, strength and durability.
Available in rigid lengths or flexible coils, all coils contain a draw string which a drawcord can be attached to. This enables the pipes and cables to be pulled through the duct after it has been installed. 90°, 45° & 22.5° bends, generally in black, are available from stock.
Loose couplers are available if there is a need to join sections together, although each coil and length is fitted with its own integral coupling.
Split Duct, for ducting existing cables, is available in OD 110 mm and above in 3m lengths and is supplied complete with a split coupler and suitable cable ties.
