Engineered specifically for tight crawl spaces and low-clearance installations, the Jackel TSF16-DR Telescopic Sump Basin brings unmatched height adjustability to groundwater management projects.
Built from heavy-duty HDPE structural foam, this innovative basin features a telescoping body that adjusts from 9-3/4″ up to 17-1/2″ high and locks firmly into place. This allows contractors to custom-fit the basin to exact trench depths and tight space limits without cutting or field modifications. Equipped with factory-drilled drainage holes (“-DR”) and non-corrosive metal threaded inserts, it delivers an efficient, contractor-grade installation that holds up against tough job site conditions.
Adjustable Telescoping Height: Easily expands from 9-3/4″ to 17-1/2″ and locks securely to adapt to precise trench depths.
