With opening widths of up to 12 m and total widths of up to 19.8 m, lift-slide systems with PORTAL HS hardware create the space for brighter and more beautiful living. With HS 400 compact bogie wheels, state-of-the-art gear technology and many other innovations, you can set 300–400 kg in motion with ease. Walls and barriers are "dissolved into thin air" and you will benefit from time savings and cost reductions throughout the entire production process.
Even heavy sashes can be moved extremely smoothly and comfortably thanks to the load being evenly distributed across eight rollers. The optimized, self-aligning load distribution ensures fluid sliding performance while minimizing wear. Compared to standard carriages, the HS 400 compact bogie rollers feature a lower design, enabling slimmer profile sections and allowing up to 12 mm more daylight as well as improved thermal insulation values (U-value).
