  • The Starline SLR is a new standard in trunking aesthetics; it has a round-round trunking profile, which is both robust and optically appealing. 
  • The trunking body features 3 fixed compartments with separate lids. 
  • You can group the cables in a simple way, and damages on the covering lids may be exchanged with little to no effort. 
  • Increased capacity - round but not bulky offering more room for cables without added depth
  • Improved aesthetics - rounded corners and a stylish profile
  • Easy install - hinged lids to support cables during installation
  • Easy to adapt - full compatibility with the established Starline® accessories like dividers, outlet boxes and housings.
