Are the SC60A-18PA and SC90A-18PA drop plates the same?

Yes, these plates have the same mounting hole dimensions and the cylinders (SC61A, SC93A and SC94A) have the same hole pattern of 3/4" X 9 1/16".

Please Note:  
  • The plates are the same but the instructions for mounting the closer/plate are different so you must follow the proper instructions based on closer being used.
  • The SC90A-18 drop plate can only be used with the SC93A or the SC94A closer.  There is no drop plate available for the SC91A closer (has a different cylinder mounting hole pattern).
