Notes: 1. Model M-2462 is self lowering and a motor brake should be used. 2. Model M-2463 may drift 0.75 in (20:1 ratio) to 2.0 in (5:1 ratio) when motor is shut off. If this is undesirable, a motor brake should be employed. 3. When ordering other than 56C-face actuators contact applications engineering at 800-477-5002.
