Hello! Thanks for reaching out to us. I don't believe the 39-253LB is what you want. The design of the base and arms are just a little too different. Instead, consider our 39-032. This is a Truth EntryGard operator, which I believe is precisely what you have installed now. Review our specs and see what you think. We also sell the 39-031 for the opposite side. Dimensions for 39-032
