The Blum AVENTOS HK-S 20K7A11 opening-angle stop mechanically restricts the maximum opening travel of a compatible current-generation HK-S stay-lift mechanism to approximately 75°. It is intended for cabinet installations where the standard opening travel would provide insufficient clearance beneath a ceiling, cornice, shelf or another nearby feature.

Stock code HI20K7A11 identifies this specific RAL 7037 dust-grey accessory. It is suitable for compatible standard and TIP-ON AVENTOS HK-S configurations, although it does not provide either opening assistance or soft closing by itself.

Restrict an HK-S front to approximately 75°

When fitted correctly to the compatible lift mechanism, the stop limits how far the cabinet front can travel upwards. The 75° position reduces the maximum opening angle while retaining access to the cabinet interior, making it useful where the available overhead space is restricted.

Measure the complete cabinet-front movement before installation. The stop limits the mechanism's travel, but it does not guarantee that the front, handle or surrounding fittings will avoid every possible obstruction. Open the completed installation slowly and confirm that sufficient clearance remains.

Check the AVENTOS generation carefully

Blum has produced different AVENTOS stay-lift generations with similar-looking opening-angle accessories. Article 20K7A11 is the 75° stop for compatible current AVENTOS HK-S mechanisms. It must not be confused with legacy AVENTOS HK article 20K7011.

This 75° version must also be distinguished from the AVENTOS HK-S 20K7A41 100° opening-angle stop. Confirm the lift-mechanism range, required angle and exact article number before ordering.

Frequently asked questions

What does the Blum 20K7A11 opening-angle stop do?

It mechanically limits the opening travel of a compatible current AVENTOS HK-S mechanism to approximately 75°.

Can it be used with both standard and TIP-ON HK-S mechanisms?

Yes, it is listed as an HK-S accessory for compatible standard and TIP-ON applications. It does not itself provide TIP-ON or BLUMOTION functionality.

Is this the legacy AVENTOS HK 75° stop?

No. This is current HK-S article 20K7A11. The legacy AVENTOS HK 75° stop is the different article 20K7011.

Is this the 100° version?

No. This product restricts the opening angle to approximately 75°. The current AVENTOS HK-S 100° stop is article 20K7A41.

Will it prevent every possible collision?

No. The available clearance must be measured and the completed installation tested carefully. Suitability depends on the cabinet layout, front dimensions and nearby obstructions.
