Large entry brass strike plates are becoming harder to find at an affordable price so we just had a number of brass strikers manufactured, this one is 5 1/2" long, 1 1/4" wide across the body and 2 1/8" wide thru the wing.  It is 3/32" thick.  

The solid center between the striker and the deadbolt measures 7

/16" and the openings are each 5/8" wide. 

The plate is reversible and lightly tapered on the wing.  The screw holes are chamferred on both sides of the plate in order to allow for tapered screw heads to embed.
