What are the removal notch options and their impact on assembly access?

Spiral rings are designed with a small 'removal notch' at one or both ends of the wire. This notch allows a screwdriver or dental pick to get behind the ring to pry it out of the groove. In tight spaces where axial access is limited, a 'slotted' end or a 'hole' end can be specified. For assemblies that must never be disassembled, a 'no-notch' design can be used. Designers must place the notch in an orientation that is accessible to the maintenance technician, particularly in deep bores where the ring might be several inches inside a housing.
