Factory Direct Supply of CE and RoHS Certified Fiber Tension Clamps for Electrical and Machinery Use

So we've been getting a lot of requests from buyers setting up overhead cable runs or machinery wiring harnesses, and the common thread is they need something that won't slip under load but also doesn't cost a fortune per unit — that's basically where these U-type clamps fit in.

Breaking load is rated at 15 kN, which is plenty for 8 to 12 mm cable diameters, and the body is PA66 with an aluminun M alloy insert, so you get good corrosion resisance without the full weight of steel, and teh surfce gets a polishing treatment as standard.

Dimensions are 330mm by 62mm by 32mm, give or take a mm on the length, and you can choose black, silver, or a custom color if you're ordering enough volume — usually 500 pieces or so to make the color change worth the production run.

They're CE and RoHS certified, ISO listed too, and we back them with a 10-year warranty, but honestly that's more for the aluminum hardware than the plastic body, which will degrade faster if exposed to direct UV constantly — not ideal for outdoor pole mounts without a shroud.

When you order factory direct from Ningbo, you skip the distributor markup, and our company can do custom packaging with your branding if needed, but the standerd bulk pricing kicks in around 200 units and lead time is typically 20 days or so, though we usually have stock for the black version.

One thing buyers don't always think to ask is that the polishing treatment isn't just cosmetic — it actually reduces friction on cable surface during tensioning, which helps avoid micro-scratches on fiber jackets, and that matters more than most people realize for long-term signal integrity.
