The triflex R e-chain is already a good protection for cables and hoses but in some application or edges on a robot an addtional protection is needed. For those situations the triflex R protector in the same size as the e-chain is the perfect extra protection for the triflex R e-chain to extend the life time of the product even more.  
This protector can simply be clipped on the triflex R e-chain of the equivalent size.
