FEATURES
The -B series round dampers are designed with a more compact actuator, and are shorter in length, saving shipping, storage and installation space. The compact actuator contains a self-aligning plastic hub which slips over the shaft but is not clamped to it, reducing the possibility of misalignment and shaft binding.
• Self-aligning shaft and actuator hub requires no adjustment.• Spring-loaded disengagement (quick blade release button) for momentary release of main gear and damper blade.
• Terminals recessed in plastic. No cover removal for wiring.
• Plastic hub protects actuator from condensation.
