GN 304.1 Straight Adjustable Levers with Push Button, Zinc Die-Cast, Threaded Stud Type, with Stainless Steel Components


Product description


GN 304.1 adjustable levers with push button have a straight lever parallel to the clamping surface. For some applications this presents an advantage due to limits of space or for visual reasons.

These levers have proven to be ideal wherever parts have to be clamped in a confined space or in a particular lever position. The insert is connected to the lever via serrations that can easily be disengaged.

Pulling the lever upwards disengages the serrations, allowing it to be swiveled to the ideal clamping position. When releasing the lever, the serrations automatically re-engage.

The push button is a design element and allows for effortless release action. However, this design is limited to applications that do not require the lever to be disassembled.
