BLASI – Bevel pinion emergency release
The BLASI Bevel pinion emergency release enables manual override of automatic door operators during power failure or emergencies through its precision bevel gear engagement. This critical safety component disengages the drive pinion from the rack, allowing free manual door movement while maintaining structural integrity. Engineered for all BLASI sliding and swing door systems, it provides compliant emergency egress and quick restoration of automated operation.
Product Details
Designed as the primary manual release mechanism for BLASI automatic door operators, the Bevel pinion emergency release features precision-engineered conical gearing that smoothly disengages the motor pinion from the door rack under spring-loaded or lever actuation, instantly converting power-operated entrances to free manual operation essential for life safety compliance. The bevel design eliminates backlash common in straight spur gear releases while distributing side-loading forces across multiple tooth contacts for reliable thousands-cycle performance.
Robust construction withstands repeated emergency activations characteristic of commercial facilities, while color-coded release levers and standardized mounting ensure technician familiarity across diverse BLASI operator platforms. Integrated detent positioning maintains partial engagement during normal operation, preventing accidental disengagement from vibration or minor obstructions.
Technicians value the tool-free release activation and self-resetting mechanism that automatically re-engages upon power restoration, while facilities managers specify this proven bevel pinion design confident in its ability to satisfy stringent fire codes, provide unobstructed egress paths, and minimize service calls across high-traffic entrances requiring guaranteed emergency functionality and operational continuity.
