description The present disclosure provides a fir tree coupling (200) for gas turbine engine parts comprising a load beam (206) having a longitudinal axis (207), a base (210), a first side (212), and a second side (214), a rail (204;217,218) extending from the base (210) of the load beam (206) between the first side (212) and the second side (214), a tooth (202) running parallel to the longitudinal axis (207) disposed on the first side (212) of the load beam (206). The rail (204;217,218) may comprise at least one of a convex sidewall (602) having a convex curvature, a concave sidewall (610) having a concave curvature, or a vertical sidewall (604) extending perpendicular to the base (210). The rail (204;217,218) may comprise a sidewall comprising a sidewall step (608) wherein the sidewall has a step (609) cut into a portion of the rail (204;217,218). The rail (204;217,218) may comprise a tapered sidewall (600) wherein the tapered sidewall extends at an angle to the base (210).
