33003-001

Chatsworth Products is a trusted bulb seal manufacturer delivering high‑quality edge sealing components for data‑center aisle containment. The Universal Bulb Seal (part number 33003-001) provides a durable, black‑finished seal that attaches to full‑height filler panel extrusions. Its design ensures a consistent seal across both full‑height and polycarbonate panels. Designed for straightforward bulb seal installation, the seal features pre‑drilled attachment points that align with standard filler panel supports. Installers can trim the 96‑inch (2438 mm) length to match site requirements, reducing labor time and minimizing gaps. This results in improved airflow management and lower cooling costs. For projects that demand custom plastic round bulb seals, the Universal Bulb Seal can be ordered in packs of two or ten, allowing flexibility in stocking and deployment. The same tooling can also produce custom plastic half‑round bulb seals when a half‑profile is preferred for specific duct configurations. These options enable engineers to tailor the seal geometry without compromising material integrity. The sealing bulb integrates seamlessly with the Build‑to‑Spec (BTS) aisle containment solution, supporting both hot‑aisle and cold‑aisle configurations in hyperscale and multitenant data centers. Its robust construction meets industry standards for fire safety and mechanical durability, making it suitable for high‑density environments. By securing the edge of blanking panels, the seal helps maintain optimal temperature gradients across the rack footprint.
