Abstract
A station protector, such as the type having pairs of arrestors positioned in adjacent wells, with screw cap enclosing the wells, is provided with positive protection by interconnecting a pair of screw caps by means which prevents turning of either screw cap, to provide access to a well, without breaking a connecting member and thus giving an indication of such turning, and access. The connecting member can be a bar attached to the screw caps, or cap member extending over the screw caps and connected to them. The cap members can be connected to the screw caps by bonding, crimping or other method.
