Rugged, low-profile protection for busy doors

The M-D Building Products 68387 Aluminum Commercial Flat-Profile Threshold is built to endure the pace of busy doorways. Crafted from heavy-duty aluminum, this threshold blends a sleek, low-profile silhouette with a robust core that resists scuffs, moisture, and dust in high-traffic spaces.
