RAM Combi-Duct Lightproof Ducting, aluminum / PVC, ø 315 mm, 10 m

- A 4-layer, multi-layer construction with an enclosing spiral made of high-strength steel wire ensures strength and durability.

- Outside made of black PVC is absolutely plant-proof and very flexible - Compared to conventional standard alloys, it offers additional airtightness.

- Due to the 4 layers (when fully extended), the tube folds into a shape with a seamless cavity, which results in a low pressure drop, no clogging with particles and a low noise level when in use.

- These tubes have a transparent layer on the inside and a black lightproof layer on the outside.

- The clear layer works effectively to minimize the noise from the film.
