With the ability to measure up to 4 1/8” of pipe, you can say goodbye to unreliable zip ties and straps and hello to convenience, precision and speed. This high-tech pipe clamp is rugged, versatile and just right; and since it’s available in a wired (TC48) and wireless (JL3LC) model – it’s a perfect match for real pros, no matter your preference.

Whether you’re in commercial, refrigeration or residential/light commercial, accuracy always matters – and we know, sometimes size matters too. At 4 1/8”, the TC48 and JL3LC offer the widest openings on the market, making them the ideal fit for nearly all large pipes. 

And because speed matters too, our patented Rapid Rail™ Sensor Technology uses electrically conductive pipe to complete the circuit and stabilize immediately, offering direct, reliable and secure connections – FAST – even on wet or damp pipes. It’s also compact and built for single-hand use (which comes in super handy for those harder to reach areas).

The TC48 features an extra long 6' tangle-free wire with Type K plug for universal use, while the Job Link System JL3LC boasts 350'+ of wireless range to communicate with both the Job Link App and the SMAN Refrigerant Manifolds, models SM380V and SM480V
