The GN 7237 Stainless-Steel Multiple-Joint Hinges are installed on the inside of flaps, hatches or compartment doors and protect against vandalism. These units increase accessibility for hatch doors.

NEW BERLIN, WI – JW Winco, Inc., A Ganter Company, a leading supplier of standard industrial machine components, now offers GN 7237 Stainless Steel Multiple-Joint Hinges with Internal Mounting Brackets and an Opening Angle of 180°.

JW Winco’s GN 7237 Stainless Steel Multiple-Joint Hinges are installed on the inside of flaps, hatches, or compartment doors to save space and ensure protection against vandalism. The hinges have a maximum opening angle of 180°, which provides optimal accessibility for hatch doors, for example.

“Use of this hinge type leaves housing exteriors free of attachments that do not match the design or that should be avoided entirely in the interests of fast and easy cleaning,” said John M. Winkler, CEO, Office of the President at JW Winco.

Stainless steel multiple-joint hinges are generally used in pairs, meaning that one type L (Left-Hand) and one type R (Right-Hand) are used per opening. For higher loads, such as from large hatches, these can be supplemented with additional hinges of either type.

The Stainless Steel Multiple-Joint Hinges are manufactured in a way that includes the angled mounting brackets, which are mounted on the housing or the door, and an intervening seven-speed, clearance-free, self-lubricated joint mechanism. Due to the movement of the joint mechanism, when opening, for example, a flap is first slightly lifted and then swung by 180°.
