• By connecting to a rod latch, it can be used for large doors that cannot be handled by rod latches with dual rollers.
• Tightening latch system completely different from conventional 3-point locks.
• With the dual roller seat (sold separately) attached to the frame side, the entire door is tightened evenly and strongly by the compression function that pulls in the roller.
• The system can be installed outside the ceiling area of the cover door.
• When waterproof is required, there is no need to apply caulking to the handle mounting part.
• Since it is installed in a place that is normally dead space, internal space can be utilized effectively.
• When used together with the 212 type hinge, it can be used as a non-handled system to eliminate the left and right side of the door itself.
• This reduces design, management, and production costs.
