The Stanley VDE Round Clamp is a hand tool designed specifically for clamping and securing electrical cables and conductors safely on the job.

Built to meet stringent safety benchmarks, the VDE‑certified insulation means you can trust this clamp around live wiring up to 1000 V without guessing about protection — that’s a big deal when you’re in tight conduits or breaker panels.

Key Features:

• VDE Insulation Safety - Certified for safe use on circuits up to 1000 V so you’re protected against electrical shock.
• Round Clamping Jaw - Grips round components and cable runs without slipping so you don’t spend extra minutes readjusting.
• Heat‑Treated Alloy Steel - The core will handle knocks and twisting without bending out of shape under daily jobsite wear.
• Ergonomic Insulated Handles - Textured grips help you hang onto it even when hands are greasy or wet — and minimize fatigue on longer installs.
• Compact 150 mm Size - Small enough to fit in tool belt but big enough for common cable diameters you’ll see in residential and commercial work.
