Interlocks
The 6940 Type Interlock is one of the most recognized in the industry. The interlock prevents the opening of the car and hoistway doors unless the car is within the landing zone and is either stopped or being stopped. Because the 6940 Type is still so common, UNITEC offers different options for its replacement and/or refurbishment.
Discover the extensive range of 6940 Interlocks, available at budget-friendly prices, with or without a spirator. Additionally, spare parts are on hand for convenient on-the-go repairs. Maximize savings on labor costs by investing in our 6940 labor-saver kits. Choose from our comprehensive selection of rebuild kits, including full service and minimum rebuilds, to access all the necessary components for refurbishing existing locks. UNITEC also provides unlocking devices that can be seamlessly integrated into any 6940 system
Complete 6940 Interlock sets
Complete sets with or without reel closers are available, as are replacement assemblies. Adaptor plates are also available (separately) to help adapt newer version 6940 Interlocks to the earlier vintage lock bolt pattern.
