B-LOCK - Steel wire rope 1.5mm - 150m on a spool BL15150

B-LOCK Steel Cable for Construction Suspension Systems

The B-LOCK steel cable with a diameter of 1.5 mm is a key component of suspension systems designed for installing electrical equipment, HVAC systems, and signage elements in construction projects. The multi-wire construction 7×7 lay (49 wires) allows for repeated bending without the risk of individual wire fractures, ensuring predictable performance under load throughout the entire service life.

The multi-strand structure evenly distributes loads and increases resistance to material fatigue during repeated bending—particularly important in installations requiring frequent adjustments or modifications. The galvanic zinc layer applied via hot-dip galvanizing effectively protects against corrosion, extending service life without the need for maintenance or replacement.

Strength Parameters and Operational Safety

Steel with a nominal tensile strength of 1960 MPa guarantees a load capacity of 35 kg as the safe working load when used with B-LOCK pulleys. The breaking load of 1460 N provides an adequate safety margin for static installations. The cross-sectional area of 1.767 mm² with an outer diameter of 1.5 mm enables precise fitting to the system's adjustment mechanisms.

The cable weight of 0.9 kg/100 m facilitates transport and installation of long lengths—one spool contains 150 meters of continuous installation, significantly reducing order frequency and logistics costs compared to multiple short segments.

System Compatibility and Application Versatility

The product is fully compatible with the entire range of B-LOCK adjustable pulleys—it can be used both individually and in dual-pulley configurations for higher loads. The dedicated diameter of Ø1.5 mm perfectly matches the suspension mechanics, ensuring stable fastening without slippage or loosening during operation.

The cable performs excellently across a wide range of applications: from lightweight signage elements and lighting fixtures to heavier HVAC components. The strand structure guarantees stable parameters throughout the service life—there is no elongation or "creep" characteristic of cheaper alternatives.

The spool, made of impact-resistant plastic, is compact and lightweight, simplifying storage and transport to construction sites or building technical rooms.
