item offers Spacer Bushing D17/D6-5 and Spacer Bushing D17/D8-15 for evening out the heights of different components. The Spacer Bushings are designed to ensure there is a big enough gap between the profiles and Karakuri/LCA components in a construction, so that cables run with perfect precision. Several Bushings can be installed one on top of the other when larger gaps need to be created.
