Four Bolt Clamp / Interlock Clamp – Heavy Duty Pipe Support & Alignment Solution
The Four Bolt Clamp, also known as an Interlock Clamp, is a heavy-duty fastening solution designed to provide strong, secure, and vibration-resistant clamping for pipes, hoses, and structural connections. Engineered for demanding environments, this clamp ensures excellent load distribution and firm grip through its four-bolt locking system, making it ideal for marine, industrial, HVAC, fire-fighting, and plumbing applications.
Manufactured from high-strength steel or stainless steel, the interlock clamp offers superior durability, corrosion resistance, and long service life, even in harsh conditions such as offshore, coastal, or high-humidity environments. The interlocking design prevents slippage and misalignment, ensuring stable performance under pressure, temperature variations, and continuous vibration.
Easy to install and remove, the four bolt clamp is a reliable choice for both permanent installations and maintenance work where safety, strength, and precision are critical.
