A universal adapter assembly for connecting a roller guide to a frame of an elevator car where an existing hole pattern in the frame of the elevator car is different from an existing hole pattern of the roller guide. The assembly includes an upper member having a hole pattern complementary to the hole pattern of the roller guide permitting the roller guide to be readily connected to the upper member. The assembly includes at least one low member connected to and disposed below the upper member. The upper and lower members each include at least one enlarged opening to permit relative adjustment of the members to compensate for the differing hole patterns of the roller guide and the frame of the elevator car. Preferably, the assembly is configured to be light weight, easy to install and capable of providing additional vibration damping.
