Hawke HF tolerant blocks are designed to accommodate cables/pipes passing through the frame. Our special design incorporates five contact points which allows the blocks to accommodate a range of different diameters and accept variances in cable/pipe diameter. Each block that a sealing range of 3-4mm without the need for any onsite modifications.
Also, Hawke’s unique inspectable colour code make installation easier, faster and allows a visual inspection of the transit when complete.
- Made of zero halogen, intumescent elastomeric polymer.
- No modification of the block needed during installation. Zero waste material.
- Four sealing grooves within the internal faces ensure correct contact all along the cable/pipe.
- Minimum and maximum sealing range is marked on the blocks. Also, the colour-coding allows for correct visual inspection. Our system can be visually inspected at a glance.
