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 Model Range
The catalog groups models 382, 383, 384 and 385 as concealed type door closers, with model selection based on maximum door leaf width, door weight and closing force.
Cleaner Door Appearance
The concealed closer layout places the closer body and arm system within the door and frame preparation, helping reduce visible surface hardware compared with ordinary surface-mounted closers.
