HDS D1 drop seal (HDSD1‑1200) is designed for wooden/timber doors with widths ranging from 1000–1200 mm. Its automatic drop-down mechanism engages when the door closes, effectively sealing the bottom gap. This helps block drafts, dust, noise, and light, enhancing energy efficiency and indoor comfort. The seal is durable, easy to install, and ideal for residential, commercial, and office doors.
