Ball catches GN 4490 are used, for example, to hold flaps and doors closed that must be opened and closed frequently and easily. The stainless steel version is especially hard-wearing and also suitable for use in aggressive environments.

The Ball catches consist of a ball housing and a retaining element that engages in the ball housing from the side or front. The installation orientation can be chosen as desired.

Beyond the typical uses, these solid and attractively designed ball catches are also utilized in technical environments. When used in profile systems, the slot width n may not be larger than listed in the table.
