Cable tie BLOW 41-225# 4.2 x 350 mm black – nylon self-locking strap

BLOW 41-225# cable tie is a black nylon self-locking strap with dimensions 4.2 x 350 mm. It is manufactured from corrosion-resistant nylon and features a serrated strap with a one-way locking head to provide secure, permanent bundling of cables, pipes and other items. The product is intended for situations that require dependable fastening with a compact profile and a smooth outer surface.

Advantages

The nylon construction offers resistance to moisture and many common chemicals while maintaining tensile strength suitable for general-purpose fastening. The serrated strap and one-way locking head ensure a reliable grip that prevents slippage after installation. Its slim cross-section and 350 mm length make it versatile for a range of bundle diameters, and the black color provides discreet appearance and improved UV resistance compared to natural nylon in many applications.

Suitable for

• Bundling electrical cables and wiring harnesses
• Securing hoses and pipes in automotive and industrial settings
• Temporary or permanent packaging and product assembly
• General organisation and cable management in homes and offices

Key specifications

• Material: nylon (polyamide)
• Colour: black
• Width: 4.2 mm
• Length: 350 mm
• Locking: one-way self-locking head with serrated strap
• Finish: smooth outer surface with serrations on the inner side for grip

How to use

Thread the tail end of the cable tie through the head and pull until the strap tightens around the bundle. Apply steady force until the desired tension is reached; the one-way locking mechanism will hold the strap securely. Trim the excess tail close to the head for a neat finish and to reduce snagging. For permanent fastening, ensure the tie is sufficiently tightened to prevent movement but avoid over-tightening that could damage cables or hoses.

Usage recommendations

For outdoor or UV-exposed installations, verify material suitability and consider additional protection if prolonged sunlight exposure is expected. Use appropriate tie width and length for the bundle size and check compatibility with cable insulation and pipe materials to avoid abrasion. Replace ties showing signs of cracking or embrittlement.
