Notes: 1. Model M-2464 and M-2465 are self lowering and a motor brake must be used. 2. Due to hight travel speed of BM-2464, it is important that a brake with a minimum response time be used. An independently controlled direct acting brake (6ft-lb for 3/4 HP Motors and 3ft-lb for smaller motors is recommended. 3. When ordering other than 56C-face actuators contact applications engineering at 800-477-5002.
