Whale SB3422 Top & Side Entry Plastic Strum Box (19mm) W-SB3422

Whale strum box SB3422 for 19mm (3/4") bilge pump hose. The 2-in-1 strainer and non-return valve features an adjustable multi-directional port to provide the flexibility of both a top entry and side entry strum box in one. The Whale strum box maintains good priming and flow, and prevents the end of the hose sucking against a flat surface and therefore allowing the water level to be reduced to a minimum. Supplied retail packed.
