Designed as a retrofit part for the BL7000 series to fit the upper coding system. This allows the unit be recoded on the door.
In case of a faulty code change, this part is designed to act as the failsafe over the rest of the mechanism, preventing internal damage through it’s failure points. If this has occurred, it’s recommended that a replacement part, such as this, is included in the setup as spindles bent back in place will be weaker and more prone to failure due to being more malleable.
