The Dual Lock Lever Handle Turn Snib has been designed and developed exclusively for single lever action to open dual lock doors, simultaneously with one action
This overcomes the existing problem of having to use a double handed action with dual locks to open a door.
The standard DLLH-33 has been enhanced to incorporate a turn snib (DLLH-33 T) which allows the top deadbolt to be activated internally via the turn snib. This does not affect the single downward action of the handle which will release both locks simultaneously.
