This is a Atlas BLMA93 N Rear Fan Grab Iron (Pack of 3). Features: Round Rear Fan Grab Irons are found on nearly all EMD locomotives from the SD35-45 and GP30-40-2. Installation Instuctions: 1. Remove the molded - on rear fan grab iron on your locomotive shell with a sharp hobby knife. 2. Use the markings from the removed grab and place the BLMA part on the shell to locate exactly where you need to drill your two holes (using a #80 drill bit). 3. Once your holes are drilled, sand down the surface to totally remove the old, molded - on grab iron if need be (though sometimes you can get things flush with just your blade). We suggest using toothless pliers to grasp the grab iron while installing. 4. Put the grab iron in place prior to gluing which will give you a good indication of how things are lining up before it is permanently in place. 5. After the grab is lined up, remove it with your toothless pliers then dab the ends in a small amount of glue and reinsert, leaving the grab iron away from (not flush with) the shell. 6. Adjust quickly as the glue sets fast. We also suggest adding extra dabs of glue to the inside of the shell where the ends of the grab iron will poke through.
