HOPO Pro Series Slim-Stile Lift-and-Slide Door okucia System

Turning the handle lowers the sash by approximately 7 mm and engages the multipoint locking system, compressing the perimeter gaskets. This coordinated action supports sealing, acoustic and wind-load performance. Final whole-door performance depends on the profile, glazing, gasket design and verified testing.

The system supports sash weights up to 300 kg, subject to the selected roller configuration. Auxiliary rollers can be added for higher-load configurations, allowing larger sash dimensions while supporting smooth and quiet travel.

Double-sided handles are available with or without cylinder preparation. A single-sided handle with a recessed pull is also available without cylinder preparation, supporting different access and locking requirements.

A buffer integrated into the drive gear helps reduce handle kickback while the sash lowers. The upper locking point is concealed within the profile chamber for a cleaner architectural appearance.

The sash can be held at selected positions along its travel to provide controlled ventilation. Performance while the sash is held open depends on the complete door design and project conditions.

When the sash is lowered into the locked position, the rollers are relieved of the sash load. This helps reduce roller deformation and wear, supporting stable long-term operation and lower maintenance demand.

The supplied product data specifies at least 100,000 opening-and-closing cycles. The coordinated structure is intended to maintain stable operation over repeated use; the applicable test method and report govern the published performance claim.

The strikers support direct screw fixing for faster assembly. The handle package includes a 10 × 10 mm spindle and M6 stainless-steel Phillips countersunk screws for through-bolted fixing.

Precision-cast stainless-steel strikers provide robust support at the locking points and help improve locking stability and resistance to deformation.

Selected hardware materials and protective surface treatments are designed to resist moisture-related deterioration and corrosion. Suitability for a specific exposure environment depends on the confirmed finish and verified test data.
