Product description

Information

GN 187.5 serrated locking plates can be installed in combination with GN 187.6 locking joint sets to create locking joints. This allows gear lever handles and retaining tubes or trays and mounts to be adjusted relative to each other at defined angles with a form-fit connection. The angle position of the serration is adapted to the connecting elements, permitting an axis-parallel or right-angled arrangement.

Held together and centered by locking joint sets, the various types can be combined together arbitrarily with identical nominal sizes d₁. GN 187.2 conical thrust springs can be placed between the locking heads during mounting, allowing a clean separation upon removal. Additional design possibilities arise from the compatibility of the locking heads with the GN 187.4 locking plates.

When welding on, type E can be easily positioned on the opposing part and fastened by means of the mounting holes d₈ (which are aligned with the serration) using dowel pins or positioning pins.
