1102 Concealed Dustproof Ware for Door
The 1102 Concealed Dustproof Ware is shown in the Tongguan catalog as a concealed door bottom sealing accessory for wind-proof, dust-proof and keeping bugs outside. It uses the same automatic sealing action: the hermetic seal rises when the door opens and falls down to the floor tightly when the door closes.
What buyers need to know first
Hardware buyers usually compare door type, opening size, fire rating, finish and access-control compatibility before asking for price.
Concealed Door Bottom Seal
Model 1102 is presented as concealed dustproof ware, helping buyers specify a cleaner door bottom detail than an exposed reveal type seal.
Automatic Sealing Action
When the door opens, the hermetic seal rises and leaves the floor; when the door closes, the frame presses the nut at the end of the seal and the seal falls down tightly.
Installation Notes
The catalog drawing shows direction setting, mechanism reversal from the left or right end, cutting to fit door size and adjustment with the supplied hexagon wrench.
