The present invention relates to an apparatus for restricting access to ports that may be disposed in a bonnet (104) to house valves (107, 108, 110 and 120 on a railcar (106). More specifically, the present invention relates to a template (1) that may be lowered over the bonnet (104) of the railcar (106) wherein the template has a plurality of differently sized apertures (40, 42, 44 and 46) to allow access to specially- sized valves (107, 108, 110 and 112). In addition, the valves may be eduction valves and/or vapor valves, and the apertures (40, 42, 44 and 46) may allow a specific-sized nozzle to have access to the eduction valves, the vapor valves or both. The template (1) may lower onto the bonnet (104) via a frame that may be rotatably attached to a structure. Further, joints (22, 24) and ball joint connections (26, 28) may be provided to allow the template to be movable so as to precisely fit over the bonnet (104)of the railcar (106).
