The 4200 Series Kale W4 is a marine-grade solid band hose clamp, manufactured in 304 stainless steel throughout — band, screw, and housing. The unperforated solid band provides a smooth, even clamping surface with no sharp edges. The all-304SS construction resists corrosion in coastal and high-humidity environments where W2 or W3 grades would corrode.

Suitable for above-waterline marine hose connections, coastal agricultural equipment, food-grade plumbing, and any application requiring the corrosion resistance of 304 stainless with the smooth clamping profile of a solid band. For below-waterline or saltwater immersion applications, W5 (316SS) clamps are recommended. Includes plastic safety guards to protect against sharp band edges during installation.

Available in boxes of 10. For a full-range workshop kit in W4, see the 4200MWK Master Kit listed separately.
