Perko Cable Clamps
Perko Cable Clamps: American-Made Marine Hardware You Can Count On
When it comes to securing cables and lines aboard a vessel, the hardware has to hold up against saltwater, UV exposure, vibration, and the relentless demands of the marine environment. Perko has been engineering exactly this kind of dependable marine hardware since 1907, and their cable clamps carry that same century-plus legacy of craftsmanship to every installation.
A Legacy Built on Vertical Integration and Quality
Five generations later, PERKO® is still a privately owned, family operated corporation, which is unusual in today's marketplace. That longevity is no accident. With full control over every step of the manufacturing process — from product design and tooling to final inspection — Perko offers consistent performance and long-term durability. PERKO® is the only domestic marine manufacturer producing die-cast bronze parts, well known for strength, uniformity, and quality. This fully integrated approach means every cable clamp leaving their modern facility spanning 440,000 square feet on 17 acres in North Miami, Florida meets the same exacting standards.
Their ISO 9001:2015 certification reflects a dedication to excellence across all operations. A key part of the Perko formula is the commitment that all products are made in the United States — even raw materials such as sheet metal, plastic pellets, aluminum, bronze, and zinc are sourced from American manufacturers.
What Perko Offers in Cable Clamps
Perko's cable clamp lineup is designed to handle the specific challenges of marine wiring and line management. Their stainless steel spring clamps are engineered for use both inside and outside the boat, providing a secure, corrosion-resistant hold on cables and hoses. The Perko Spring Clamps feature stainless steel construction for lasting quality and are available in two sizes: Size #1 for 5/8" to 1-1/4" diameter with a 1-1/2" projection, and Size #2 for 1" to 1-3/4" diameter with a 2-1/4" projection — sold one pair per package.
Perko also offers cable straps and rope clamps crafted for tiller and steering system applications. Designed for 1/8" and 3/16" rope and measuring 1-1/4" x 11/16", these chrome-plated zinc clamps are sold in pairs — a practical choice for sailors and powerboaters alike who need reliable, compact hardware for line management.
Why Marine-Grade Matters in Cable Clamps
Standard hardware-store clamps simply aren't built for the marine environment. Exposure to bilge moisture, deck spray, fuel vapors, and constant engine vibration demands materials and finishing that only purpose-built marine products can deliver. Perko's stainless steel and chrome-plated zinc options are specifically selected to resist corrosion and maintain a secure grip over thousands of hours of use — whether you're routing electrical cables through a bilge or organizing steering lines in a cockpit.
For boaters who take their vessel's reliability seriously, choosing proven hardware from a manufacturer with over a century of marine-specific engineering experience makes a tangible difference.
