Two Precautions for Use
When installing the mandrel, it should be kept on the center line of the drum and extend out of the round hole of the auxiliary plate as much as possible to ensure that the door does not fall.
When welding the mandrel and the drum, weld them as fully as possible, as desoldering is most likely to occur here.
The mold seat should be sealed and welded firmly.
Conventional double curtain accessory panels are designed for right installation when leaving the factory. Please specify when purchasing when installing on the left. For safe use, ensure that the pressure sprocket is under the board.
The main differences between three large boards and small boards
Large boards are used where rolling shutter doors need to be packed. Large boards are convenient for making boxes. In other cases, small boards can be selected to save costs.
