Adjustable lever GN 300-30-M5-20-SW Z029707

Adjustable lever – precision and functionality in every detail

The GN 300-30-M5-20-SW adjustable lever is an element used for convenient and precise locking or adjustment of position. Made of zinc die-cast, it is characterized by high strength and resistance to loads. A wide range of available finishes allows it to be adapted to the aesthetics of a specific application. The design based on a multi-carb and return spring ensures reliable and fast operation.

Construction and application

GN 300 levers are ideal wherever it is necessary to lock elements in a limited space or in a specific position. The mechanism of action is based on the principle of clutch engagement after pulling the handle, which allows for precise adjustment, and then automatic locking thanks to the return spring. This solution works both in professional applications and in everyday devices. Different stem lengths (l1) and threads (M3, M4, M5, M6) are available, allowing adaptation to specific mounting needs.

Finish and materials – durability and aesthetics

GN 300 levers are available in various finishing options:

• Epoxy resin coating: provides resistance to corrosion and mechanical damage. Available colors include black (RAL 9005), orange (RAL 2004), red (RAL 3000), silver (RAL 9006) and graphite (RAL 9011). Matte finish (SW) provides an elegant look.
• Chrome-plated: gives the lever an aesthetic appearance and increases resistance to corrosion.
• Uncoated: for applications where a raw, industrial finish is required.
• Black oxidized steel: provides durable corrosion protection and an elegant appearance.

The body is made of zinc die-cast, the connecting screw and return spring are made of black oxidized steel – guaranteeing reliability and long-term use. All elements work together smoothly, ensuring comfortable operation.

The body material is zinc die-cast, the connecting screw is made of black oxidized steel, and the return spring is also made of black oxidized steel. The thread size is M5, the stem length (l1) is 20 mm, the stem diameter (d1) is 10 mm, the outer diameter (d3) is 13 mm, and the total height (h1) is 24.5 mm.

Thanks to the wide selection of available models – differing in dimensions and thread type – GN 300 levers find application in many industrial sectors, mechanical engineering and in precision devices. Installation is simple and intuitive, and the solid construction guarantees long-term reliability even in harsh working conditions.
