Electricians and pipe fitters rely on the OBO BS-H1-K-40 FT U-bolt clamp to secure conduits, cables, and pipes with diameters from 34 to 40 mm. Its hot-dip galvanized steel body withstands harsh indoor and outdoor environments, making it a go-to for industrial installations, outdoor cable runs, and corrosion-prone areas.

Why choose it

The hot-dip galvanized coating provides excellent corrosion protection, ensuring long service life even in outdoor or damp conditions. The U-bolt design offers a secure, vibration-resistant grip on pipes and cables, while the M6 threads allow for quick installation with standard nuts. Its non-combustible steel construction adds fire safety, and the conductive material supports electrical bonding when required.

Ideal use cases

• Securing electrical conduits and cables on walls, ceilings, or cable trays
• Mounting pipes in plumbing and HVAC systems
• Outdoor installations exposed to weather and UV radiation
• Industrial environments with high corrosion risk

Good to know

The clamp is part of the OBO BS-H1-K series, known for robust construction. It does not include nuts or washers, so order M6 hex nuts separately. The metallic grey finish blends with standard galvanized hardware. For optimal clamping, ensure the pipe or cable diameter falls within the 34–40 mm range.
