Trim Tim 13 has similar dimensions and features to Downhill Dan 14, including the added feature of recessing trims to cover the cut edges of joinery or plasterboard when recessing. Also featured are small ribs either side of the profile which allow Trim Tim 13 to be friction-fitted into an 18mm routed slot in joinery without the need for screws. The 13mm depth provides “dot-free” lighting in building materials as thin as 18mm.
