Built for confidence in use, this heavy version offers opening angles of 75°, 90° or 110°, making it ideal for cabinets, hatches, and access panels that need reliable holding power.

Thanks to its precise mounting specification—using sheet metal screws positioned at a 37 mm distance from the edge—installation is straightforward and secure. The stay is finished nickel plated, providing an attractive look and helping it resist wear for long-lasting performance.

Designed for practical installation, the stay supports cabinet heights from 250–700 mm and is suitable for lid weights of up to ≤12 kg (please refer to the sample measurements table for exact fit).

Also suitable as a flap stay, this one-piece flap fitting version pairs expertly with zinc-alloy hardware for dependable strength. For ordering, you may need to purchase the recommended screws separately: Ø 3.5 raised head (Hospa Ø 3.5) or Ø 5 mm countersunk (Varianta Ø 5).

FAQ

Product Details

Can this flap and lid stay be used for both flaps and lids?

Yes. The Duo Forte Flap/Lid Stay is designed to work as a flap stay as well as a lid stay, making it a practical choice when you need consistent support on different cabinet opening styles.

Which opening angles are available for part 373.66.642?

It supports 75°, 90° or 110° opening angles. Choose the angle that matches how far you want the flap or lid to open, for easier access and comfortable operation.

How do I know the 37 mm distance from edge is correct for my cabinet?

The stay is set up for sheet metal screw mounting at 37 mm from the edge. Measure your planned screw position from the relevant edge before installation to ensure the brackets align correctly with your cabinet and flap or lid panel.

What cabinet height and lid weight is it suitable for?

Cabinet height range is 250 to 700 mm and the lid weight limit is up to 12 kg depending on the application. For best results, match the stay and mounting to your specific flap or lid dimensions.

Is it suitable for right and left hand installation?

Yes, it can be used for both right hand and left hand fittings. During setup, fit the components for the correct side so the stay holds the opening reliably.

Does it come with all the mounting parts, or do I need extra brackets?

It is supplied as a complete set including 1 lid stay, 1 mounting bracket for cabinet, and 1 screw on bracket for flap. You will still need the correct screws for your chosen screw type, which can be ordered separately.

What screws should I use, and what finish is included?

Use sheet metal screws as specified for this system. The stay is nickel plated for a durable finish, and you may need to order the recommended screw sizes separately, using the order reference guidance provided.

Why are there different screw recommendations in the order reference?

Different installations may require different screw head styles, so the order reference lists suitable screw options. Using the recommended screws helps the stay sit correctly and maintains secure fixing for everyday opening and closing.
