Gasket is .032" thick with a 12.250" x 4.00" opening that can be cut to fit many blower applications for roots or screw blowers. Works well for retro type roots blower as the gasket extends out 2.00" past the center of the front stud hole and 4.00" past the center of the rear stud hole. Gasket is made in the USA so don't trust cheap knock off versions.
