The 48" Dark Bronze Anodized U-Shape Door Bottom is designed for use on 1-3/4" thick doors to provide weather sealing. Constructed from aluminum, this door bottom features a drip cap that diverts rain away from the door surface. It is suitable for use with saddle thresholds to maintain a seal against the elements. The unit includes a vinyl insert with a 1/2" height to assist in keeping out weather. The door bottom has an overall width of 1-3/4" and a front face height of 1-1/4". It is designed for standard door applications and comes with slots drilled for the included No.6 x 1/2" pan head screws for installation. The dark bronze anodized finish provides a consistent appearance for exterior door hardware. This door bottom is intended for use on doors that require protection from environmental factors. The aluminum construction provides a stable frame for the vinyl seal, which contacts the threshold to block drafts and moisture. The pre-drilled slots allow for adjustment during the mounting process to ensure proper alignment with the door bottom edge. This component is a standard part of door weatherization systems, helping to maintain the interior environment by sealing the gap between the door and the floor or threshold.
