This KN is built exactly like the Garretson KN regulator’s however is by a different company. These are awesome regulator’s! The lock-off adjustment above the inlet is fully adjustable unlike the Garretson’s which for the most part are no longer adjustable.
This regulator can handle up to 0.5 PSI; 8 ounces; or 14″ WC. The inlet is 3/4 FNPT and the outlet a 3/8 FNPT.
