The Standard Tiehack Large Drain Gully is the most popular heavy duty unit, which is bead blasted with easy access for Rodding.
It has a larger construction and basket capacity compared to the Tiehack HD Drain Gully.
This Drain Gully is available in two outlet sizes to accommodate different flow rates.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that ASPEN by John Lord is consulted before specifying.
