The Jackel-SF22 is our premium residential sump basin. Constructed from ultra strong, heavy duty structural foam, the Jackel-SF22 will provide decades of unfaltering service. The Jackel-SF22A has our strongest and thickest rim, the 360 deg EZ Grab&rade; handle. It also incorporates our heavy duty, non-corrosive nylon encapsulated inserts allowing the Jackel-SF22 to be gas/radon tight and prohibits odor escape. The ultra-strong hex reinforced bottom will not buckle, deform or puncture; even under the harshest soil or ground water conditions.
