Manufactured by MALCO Products, Inc. - Annandale MN
Assigned to MALCO Products, Inc. - Annandale MN

The MALCO "Eagle Grip" was introduced as COVID disrupted commerce and the economy. The "EAGLE GRIP's" high price point was another factor leading to poor sales and production ceased after a couple of years.
