The National Hardware N248-310 is a zinc-plated wire cable clamp designed to create a secure loop or eye on 3/8-inch steel cable. This precision-engineered hardware piece is crafted from malleable iron with a durable zinc coating that resists rust and corrosion, making it ideal for outdoor, marine, and industrial applications where moisture and salt exposure are concerns.
The clamp features a grooved saddle base that locks the rope firmly in place, delivering a strong, non-slipping connection that reduces wear and prevents accidental release. Its boxed-loose construction allows for quick positioning and easy tightening without special tools, saving time on the job site.
