NSi 540 Self-Locking Nylon Cable Tie, Natural

The NSi 540 Self-Locking Nylon Cable Tie, Natural is a Nylon 66 cable tie built for everyday cable and wire bundling in commercial, industrial, and residential electrical work. This family is available in sizes ranging from 5" through 22", so electricians, contractors, and maintenance crews can match tie length to the bundle diameter and tensile demand of the job at hand. Every tie in the lineup shares the same self-locking head design, natural color finish, and Nylon 66 construction, giving installers a consistent, dependable hold whether they're securing a small harness or a large panel wire bundle. Tensile capacity scales with tie length across the range, so smaller ties suit light-duty bundling while the longer options handle heavier or bulkier cable runs.

Key Features

  • Size Range: Available in 5", 8", 11", and 22" lengths to fit a wide range of cable, wire, and harness bundling tasks around panels and enclosures.
  • Durable Construction: Molded from Nylon 66 across every size for long-term strength, flexibility, and resistance to everyday wear, handling, and environmental exposure.
  • Self-Locking Head: Self-locking head mechanism allows fast, one-time tightening for a secure, tamper-resistant hold that will not back out once installed, on any length in the lineup.
  • Tensile Capacity Scales With Length: Tensile rating increases with tie length, so the shorter 5" tie suits light bundling while the 22" tie is suited to larger, heavier bundles.
  • Color: Natural color finish across the range for a clean, low-profile appearance in exposed and concealed wiring runs where a neutral look is preferred.
  • Application: Purpose-built for cable bundling tasks across new construction, retrofit, and maintenance electrical work, from small harnesses to large conduit and cable runs.

NSi NSI850 – Frequently Asked Questions

1) What lengths do the NSi natural nylon cable ties come in?
Four lengths are offered: 5 inch (part 540), 8 inch (850), 11 inch (11502), and 22 inch (22250). Pick by bundle diameter, not by cable count. The 5 inch handles small panel and low-voltage bundles, the 8 and 11 inch cover typical branch circuit and data runs, and the 22 inch is for large harnesses, conduit groups, and strapping bundles to a rack or ladder tray.
2) Is a 40 lb tensile cable tie strong enough for panel wiring and data cable?
Yes for that work. The 5 inch NSi tie carries a 40 lb tensile rating, which the manufacturer positions for low-voltage wiring, data cable, and general cable management in panels and enclosures. It is a bundling tie, not a load-bearing or suspension strap, so don't use it to hang or support cable weight from structure.
3) Can the NSi self-locking cable tie be loosened and reused?
No. The head is a self-locking, one-way pawl design, so it tightens once and will not back out. If you expect to add or remove conductors later, leave slack or plan on cutting the tie off and replacing it. That same one-way action is what makes it tamper-resistant once installed.
4) What material are these cable ties made from, and does the natural color matter?
Molded from Nylon 66, with a natural (undyed) color. Natural nylon is the standard indoor-use tie. For outdoor or sun-exposed runs, specify a UV-stabilized black tie instead, since undyed nylon is not the one you want sitting in daylight. Inside panels, enclosures, junction boxes, and concealed runs, natural is the normal choice and blends with most wiring.
5) Are these NSi cable ties made in the USA for buy-American specs?
Country of origin is the United States. If your project carries a domestic-preference clause, that is the origin on record for these NSi nylon ties. Government, healthcare, and education procurement usually wants that stated on the submittal, and the manufacturer spec sheet is available for the package.
6) How many cable ties come in a pack?
They ship 100 to a pack. For MRO stockrooms and multi-trade crews, that is a practical shelf quantity per length, and buying two or three lengths keeps one bin covering most bundling on a job without splitting orders.
7) Do I need a tension tool to install these, or can I pull them by hand?
Hand tightening works. Feed the tail through the head, pull to tension, and the locking pawl holds. A flush-cut tool only matters if you want the tail trimmed clean inside a panel, which most electricians do for appearance and to avoid a sharp stub against conductors. No tool is included with the ties.
