The Blum AVENTOS HF 21F8020 dark grey cover-cap set provides the finishing covers and operating switches required around a compatible SERVO-DRIVE bi-fold lift installation. Its handed left and right covers conceal the cabinet-side mechanism housings, while the supplied switches and distance bumpers complete the documented cover-set package.

This genuine Blum set is designed for the original AVENTOS HF system. It is useful when assembling the specified SERVO-DRIVE configuration or replacing the matching covers and accessories on an existing installation. Confirm part number 21F8020, the dark grey finish and the mechanism generation before ordering.

Made for AVENTOS HF with SERVO-DRIVE

AVENTOS HF is Blum's bi-fold lift system for two-part fronts that fold together as they rise. Part 21F8020 is the cover-cap set for the SERVO-DRIVE version of this original HF generation. It should not be confused with the standard mechanical cover set 20F8020, the earlier SERVO-DRIVE set 21F8000 or components for AVENTOS HF top.

The covers are finishing components and the switches form part of the user interface for a compatible powered installation. They do not generate lifting force and cannot convert an incomplete mechanism into a working SERVO-DRIVE system by themselves.

What is included?

• 1 × SERVO-DRIVE cover cap, left
• 1 × cover cap, right
• 2 × branding elements stamped with the Blum logo
• 2 × SERVO-DRIVE switches
• 6 × Blum distance bumpers, 5mm diameter

The drive unit, power supply, cables, lift mechanisms and telescopic arms are not part of this cover set.

Product details

Check compatibility before ordering

1. Confirm that the cabinet uses the original AVENTOS HF bi-fold system.
2. Confirm that it is equipped for SERVO-DRIVE rather than standard mechanical operation.
3. Match Blum part number 21F8020 and Hart SKU HI21F8020DG.
4. Check barcode 9009494504873 where the original packaging is available.
5. Verify the dark grey finish against the existing installation.
6. Do not assume compatibility with AVENTOS HF top or the older 21F8000 set.

What else is needed for a powered lift?

A complete installation requires correctly selected AVENTOS HF lift mechanisms and telescopic arms, compatible hinges and plates, a suitable SERVO-DRIVE unit, distribution cable, power supply and associated electrical components. Select those parts for the cabinet dimensions, front weight and system generation using Blum's planning information.

Questions and answers

Is this the standard AVENTOS HF cover set?

No. This 21F8020 set includes SERVO-DRIVE covers and switches. The standard mechanical cover set has a different part number.

Are both mechanism covers included?

Yes. Blum specifies one left SERVO-DRIVE cover cap and one right cover cap, together with two logo elements.

Does the set include the switches?

Yes. Two SERVO-DRIVE switches are included, along with six 5mm distance bumpers.

Is the SERVO-DRIVE motor included?

No. The drive unit, power supply and cabling are separate system components.

Will this fit AVENTOS HF top?

Do not claim that it will. This set is documented for the original AVENTOS HF generation, while HF top uses a different component system.

Is this the same as 21F8000?

No. Hart lists 21F8000 and 21F8020 as distinct products with different barcodes. Match the exact part number and physical installation.
