The new tube winding system: this development improves slat closure, especially in the lower part of the blind and enables a better parallelism of the bottom rail and also has a mechanical limiter' incorporated. The blind size feasibility is also increased by almost 20%.
Polymer surface coated L shaped side-guides, the so called no-dust' coating, that reduces the friction between the slats and the side-guides during the raising and lowering function, preventing dust formation and greatly reducing contact noise.
Standardisation of the 30mm adjustment to the L-profile for easier spacer frame assembly.
Kevlar reinforced internal cords: to ensure greater cord strength whilst minimising cord shrinkage due to high temperatures (1/3 the value of comparable polyester cord).
This new SL27C system retains the same cavity (27 mm) and the same frontal magnetic control, therefore preserving all the aesthetic features of the existing system.
