一般房間門片下方與地板間縫隙自行改善方式

由於門片與地板之間必須有縫隙，這樣門才能開關自如，相對的也成為聲音或氣味或光線的傳導路徑。

因此自行改善的方法應該依據縫隙大小，地板材質或預算而有所區分。

1. 地板屬於硬質又耐磨時，縫隙小於2.5公分即可裝306AV固定型可抽換阻尼氣密條。
2. 地板屬於硬質又耐磨時，縫隙小於2.5公分大於0.9公分即可裝211AV固定型可抽換阻尼氣密條。
3. 地板屬於硬質又耐磨時，縫隙小於2.5公分大於0.9公分，門片會淋雨或水洗時即可裝210AV固定型可抽換阻尼氣密條。
4.地板屬於一般木質或塑膠地板時，縫隙小於2.5公分即可裝4131APKL自動升降型可抽換阻尼氣密條。
5.地板屬於地毯時，縫隙小於2.5公分即可裝4131ANBL自動升降型可抽換阻尼毛刷條。

以上所有阻尼條均符合美國國家UL與ASTM氣密與防火等多重國際認證標準。
 ●100%由美國逾50年專業隔音五金廠商製造。
 ●免拆門扇直接鎖在門門扇底部，自行安裝非常簡易。
 ●兼具氣密與防火或隔音等多重效果。

Automatic door bottoms consist of an aluminum case which surrounds a movable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold.   Most models are now available with nylon brush (NB) seals. The nylon filaments conform extremely well to irregular surfaces such as carpet, stone and grout lines.   Especially over uneven surfaces provide excellent seals to keep out draft, dust, moisture, insects, fumes, light, and sound.  The line includes models which can be mounted to either wood or hollow metal doors.  End plates are provided for all mounting applications.  All automatic door bottoms seal up to a 3/4" gap under the door.  Available in any size ranging from 30" to 36"(or others). All  automatic door bottoms can be trimmed down by as much as 2" (stock lengths only). If non-stock sizes are ordered, order must note need to trim 2 inches from the size ordered.  Lead line available upon request; consult Customer Service for options on profiles. The drop-bar seal actuation mechanism (all models) causes the drop-bar seal to always actuate on the hinge side first. This feature prevents the seal from skidding along the floor / threshold while the door is being closed. Door hang up will not occur.
