For over 40 years, JW Winco has been a standard setter for adjustable levers. The GN 300 is a timeless yet modern standard part that can be used in almost any context. It is also the basis for a hand-lever family that has been successively expanded by JW Winco, with variations for specific applications or with special dimensions and additional functions.
An enlarged circular clamping surface can also be found in the GN 300.4. It integrates an axial ball bearing into the washer, which reduces friction during tightening -- and allows a doubling of the clamping force.
If specially tipped studs are needed, try the GN 306 -- it offers brass- or plastic-tipped studs, hardened tips, ball pins, or circular thrust points to gently distribute the force.
The Stainless Steel variants GN 300.5 (matt shot-blasted) and GN 300.6 (electropolished) are intended for applications in corrosive environments. In particular, the special geometry and external hexagon retaining screw make this unit less susceptible to soiling or standing liquids.
Meanwhile, the GN 305 in Hygienic Design is certified by DGUV Test to meet high hygiene standards. It combines zero dead space with a solid stainless steel handle and a hygienic seal between the threaded stud and the disengageable handle body, as well as against the contact surface.
The original model GN 300 has also been further optimized. It is now available with a markedly shorter handle that reduces space requirements with a length of 0.87 in. (22 mm) and limits the applied torque during tightening. This variant is intended for light applications, such as with M3 and M4 threads.
The GN 300 zinc die cast handle is available in a variety of coating colors. The bushing and retaining screw are made of non-rusting stainless steel in variant GN 300.1, while GN 300.2 features zinc-plated and blue passivated steel -- all state of the art, as always, from JW Winco.
