Straight Thru Strain Relief Bushings
Straight‑Thru Strain Relief Bushings, also known as straight through cable bushings, nylon strain reliefs, and panel mount cable bushings, are designed to secure and protect cables as they pass through panel cut-outs. These bushings are most commonly used for both flat and round cables in electrical enclosures, control panels, machinery, and telecommunications equipment across the UK. Their main function is to provide strain relief, absorbing pull, twist, and vibration to prevent cable fatigue or accidental disconnection. Manufactured from high-grade nylon 6/6 and certified to both UL and CSA standards, these bushings are chosen for their resilience, simple push-fit installation, and ability to maintain safe, neat cable management. Available in multiple sizes to suit panel thicknesses from 0.8 mm to 4 mm, they help prolong the life of both the cable and the equipment, reducing maintenance and downtime.
