• a fire protection sprinkler including a body having an inlet, an outlet, an internal passageway extending between the inlet and the outlet along a central sprinkler axis, and an external thread formed about the central sprinkler axis, the fire protection sprinkler including a pair of spaced apart frame arms disposed in a plane and extending axially from the body and converging toward one another to from an apex centered along the central sprinkler axis and spaced axially from the outlet, the fire sprinkler including a thermally responsive trigger assembly disposed along the sprinkler axis and a fluid deflection member affixed to the apex and centered along the central sprinkler axis with the apex between the thermally responsive trigger assembly and the fluid deflection member;
• and
• a protective device strapped about the fire protection sprinkler to at least partially surround the thermally responsive trigger, the protective device including:
• a first protective member and a second protective member opposed from one another about the plane with at least one of the first and second protective members including an external torque assist surface of the protective device;
• a hinge connection between the first and second protective member to pivot the first and second protective members with respect to one another between a closed configuration and an open configuration;
• a releasable lock arrangement to lock the first and second protective members in the closed configuration;
• and
