SKU : WOR-TOO-1074
The RIDGID 20973 SeekTech 4-Inch Inductive Signal Clamp is a durable yellow clamp designed to let you trace metallic pipe, cable, and other conductive lines. It works with RIDGID SeekTech ST-305 (model G2159096) and ST-510 (model G2539957) transmitters, and comes with 16 feet of cable so you can connect quickly and get to work.
Setup is simple: connect the clamp’s 16-ft cable to your compatible RIDGID transmitter, open the 4-inch jaw around the metallic pipe or cable, and close it. The two built-in LEDs confirm that the clamp is receiving and transferring the signal. An integrated adapter lets you attach a hot stick for reaching overhead or hard-to-access lines.
Inductive clamping lets you isolate and trace a specific utility line without making direct metal-to-metal contact. This is especially useful when identifying underground or encapsulated lines before you dig or bore. The 4-inch opening fits common pipe and cable diameters, and the rugged construction is built for field work.
Backed by RIDGID’s full lifetime warranty, the SeekTech 20973 is an investment in reliable locating. The yellow housing and LEDs make it easy to spot on a jobsite. It’s a practical addition for utility locators, plumbers, electricians, and contractors who use SeekTech locating equipment.

Works as intended.
Used this with my SeekTech transmitter to trace a hidden line. It picked it up perfectly. The clamp is sturdy.
I'm a utility locator, and this clamp is a must-have. It fits on 4-inch pipes easily and transfers a strong signal. The build quality is typical RIDGID—solid and durable. It's a bit expensive, but it's worth it for accurate locating. I've used it on dozens of jobs with no issues.
Great for finding buried lines. Saved me a lot of digging. Easy to connect.
Good product.
I've been in the plumbing trade for 35 years. This clamp is easy to use and works with my newer transmitter. It's solidly built and should last a long time. The only thing is the price is a bit high, but you get what you pay for. I recommend it to any plumber.
Does the job. I had no problem hooking it up. Signal was clear.
