The Promax Installation Anchor is a cost-effective solution to holding Underground Tanks secure while backfilling and compacting.
Due to the cylindrical shape of the Underground Tanks they can ‘ride-up’ when being backfilled and compacted around the sides. These anchors ensure the tank stays in the correct position enabling more thorough installation.
- Modular – 1 x Strap & Anchor pads per meter.
- Cost effective
This product is not suitable for use on our 1.9 Underground Tanks.
