Sigma is Tycab’s cost-effective cable tie range for jobs where the installer needs dependable bundling but does not require the heavier tensile ratings of premium ranges. Tycab states that Sigma ties are made in Nylon 6 and use lower widths to deliver a more economical option for standard-duty work. They are best used in packaging, warehouse kitting, light electrical bundling, export preparation and routine indoor fastening where budget, volume and basic reliability are the main buying criteria.
