Pemko 18061CNB84 84" 7' 180 Degree Aluminum Retainer Weatherstrip with 5/8" Nylon Brush Clear Aluminum Finish

The 18061CNB84 door sweep installs on the bottom of exterior doors to seal air gaps and improve energy efficiency in commercial and institutional buildings. This aluminum retainer holds a 5/8" nylon brush that flexes to follow door and threshold irregularities. Pemko designed this 84-inch sweep for single or double door applications where weatherization matters.

The dense nylon brush compresses against thresholds and floor surfaces to block air infiltration while allowing smooth door operation. The clear anodized aluminum casing mounts with included hardware and measures 3/4" high with the brush extending another 5/8" for total height of 1-3/8". This creates effective sealing without dragging or binding during door swing.
