A fire barrier transition ( 10,110,210,310 ) comprises a first section ( 130,230,330 ) to mate with a first fire barrier ( 14 ) in a first expansion joint ( 16 ), a second section ( 132,232,332 ) to mate with a second fire barrier ( 18 ) in a second expansion joint ( 20 ), and a center section ( 134,234,334 ) therebetween to seal a gap ( 12 ) between the barriers ( 14,18 ). The first section ( 130,230,330 ) and the second section ( 132,232,332 ) each present either a convex or a concave cross-section with two sidewalls ( 136,236,336 ) and a bight section ( 138,238,338 ) therebetween. Thus, the transition ( 10,110,210,310 ) preferably presents a specific shape with the first section ( 130,230,330 ) and the second section ( 132,232,332 ) each presenting channels aligned at an angle between the joints ( 16,20 ). The barriers ( 14,18 ) can slide between the sidewalls ( 136,236,336 ) and engage the bight sections ( 138,238,338 ), thereby mating with and sealing to the first section ( 130,230,330 ) and the second section ( 132,232,332 ).
