The triflex® RS dresspack uses integrated fiber rods to create constant tension and prevent conduit looping. It has a low installation height making it ideal for low head room applications. With very few moving parts (no springs), it is ideal for high particulate environments. The RS dresspack also has various benefits because it is excellent for dirty environments, has up to 670mm of retraction, has available cover for mounting junction boxes, is available in 6 sizes, and it's low profile.
