JUMBO BARREL STRAINER - Heavy duty barrel strainer gives maximum flow capability. The impact resistant polymer won’t dent when dropped and won’t corrode even in contaminated water. The wavy straining pattern resists debris sucking flat against the holes. 240 holes total 48 square inches of flow area. An oversize loop makes tying off the strainer easy. The coupling is made from hard anodized aluminum and rotates easily on a polymer bearing ring.
