Product overview

Hawke HRTO Round Transit Frame is a fire-resistant sealing solution designed for multiple cables or pipes passing through circular apertures in walls, bulkheads and decks. With its unique compression-bolt system, the HRTO Frame expands radially to form a secure seal, eliminating the need for an external compression system and streamlining the installation process.

Hawke HRTO Round Transit Frame

Manufactured from intumescent elastomer polymer with a choice of stainless or mild steel plates, the Hawke HRTO is engineered for high-temperature, high-stress environments. Its open-frame design allows for post-installation fitting after cables or pipes are already in place, with no extra tools required.

The HRTO Round Transit Frame seamlessly integrates with Hawke Sleeves – whether welded, bolted or caste – and works with standard HF blocks for a versatile sealing solution in demanding applications. Providing reliable, adaptable protection, the Hawke HRTO Round Transit Frame is ideal for projects requiring robust, easy-to-install fire-rated seals.
