Feature: Straight strut joiner provides direct, inline connections for B-Line struts, sized to fit a 1 in height by 4.5 in length profile. Business Impact: Precise dimensions reduce misalignment and field adjustments, speeding up assembly and minimizing rework in panel and enclosure installations. Application: Use this joiner to bridge sections of 1 in high strut channels on electrical enclosures, control panels, and cable-management runs, especially where space is tight or routing requires a clean right-angle transition. Feature: 12 gauge steel construction delivers robust rigidity and strength. Business Impact: High stiffness resists bending and maintains alignment under vibration, extending service life of mounted components. Application: Ideal for commercial and light industrial installations where dependable support is critical and long-term performance is required. Feature: Includes 2 cam screws for fast, secure attachment. Business Impact: Accelerates field installation, reduces time spent hunting for hardware, and improves repeatability across multiple assemblies. Application: Install on straight strut runs in B-Line systems for reliable connectivity in panel assemblies and channel applications. Feature: Compact footprint at 1 in height, 4.5 in length, 1.62 in width; weight 0.34 lb. Business Impact: Dense layouts become feasible, handling is easier, and shipping costs drop due to lighter weight. Application: Perfect for tight spaces around enclosures and within crowded racking or cable-management paths. Feature: UL Listed certification ensures electrical-safety compliance. Business Impact: Regulatory acceptance reduces risk of non-conformance and simplifies procurement documentation.
