Security Cable Ties | Tamper Evident Secure Cable Ties & Security Zip Ties
When a cable tie is cut, moved, or tampered with, someone needs to know. Security cable ties solve both sides of that problem in one product: they bundle and secure your cables with a self-locking nylon fastener that cannot be removed without visible evidence of interference, and they give you a large writable flag area on the head to record the serial number, circuit ID, inspection date, or asset code directly on the tie. One cable tie. Two jobs. Complete cable security and identification in a single step.

Why Choose Shangbo Plastic Security Cable Ties
Every competitor sells cable ties. We manufacture secure cable ties that do two jobs at once — seal the bundle and identify it. Here is why engineers and procurement teams specify Shangbo.
Writable Flag Head — Mark, Identify, and Track Every Cable
A cable tie that secures but cannot be identified is only half a solution. Our security cable ties carry a large writable flag area on the head — write the circuit ID, serial number, installation date, or inspector code directly on the tie with an oil pen. The information stays with the cable, not on a separate label that can be lost or detached.
Tamper Evident Seal — Visible Evidence if Disturbed
Our SBS-MKT security ties use a self-locking ratchet that engages permanently once closed. To remove the tie, it must be cut — and a cut tie is immediately visible to any engineer or auditor checking the installation. This tamper evident seal property makes our security cable ties the correct specification for panels, equipment cabinets, and cable management systems where unauthorised access must be detectable.
Nylon 66 UL 94V-2 — High Strength, Not Recycled Material
Our nylon cable ties use 100% virgin Nylon 66 with UL 94V-2 flame certification. High strength tensile performance from 18 lbs up to 50 lbs across the range. Heat-resisting, acid and erosion resistant, good insulation. We do not use recycled or mixed nylon — material certificates available on request.
Two Flag Styles — Horizontal and Tall Vertical for Every Installation
The horizontal flag (100MKT / 205MKT / 200MKT) is the correct choice for open cable trays and panel runs where flags are read from the front. The tall vertical flag (110MKT) is specified for dense cabinet wiring where cables are closely packed and horizontal flags would be blocked. Both styles deliver the same nylon cable tie performance — the orientation is chosen for readability in your specific installation.
Multiple Colors Available — Custom Colour and OEM Ready
Standard security ties ship in white and blue. Multiple colors are available for OEM orders and colour-coded security systems — use different colours to identify different zones, teams, inspection periods, or security clearance levels. Custom Pantone shades and private label packaging available for qualified volume accounts.

Professional Selection Guide
Four sizes, two flag orientations, and multiple color options — use these six steps to specify the correct security tie before you order.
Confirm Your Identification Requirement
If you need a cable tie that provides both tamper-evident sealing and clear identification, the SBS-MKT series is the right choice. It allows you to mark asset codes, circuit IDs, and serial numbers while securely fastening cables in a single installation.
Choose the Right Flag Orientation
Select the flag style based on how the installation will be viewed. Horizontal flag models are ideal for open cable runs and panel fronts, while the vertical flag design is better suited to dense wiring systems where adjacent cables may obstruct visibility.
Match Bundle Diameter
Measure the outside diameter of the cable or bundle before selecting a tie. The smaller SBS-100MKT and SBS-110MKT models fit bundles up to 22mm, while the larger SBS-205MKT and SBS-200MKT versions accommodate bundles up to 50mm.
Select the Required Strength
Choose a tensile strength that matches the load requirements of your application. Lighter-duty models are suitable for cable identification and small bundles, while larger versions provide the holding power needed for heavier cable groups and demanding installations.
Choose Flag Size and Colour
White and blue are the standard colour options, with white offering maximum readability for handwritten marking. For applications requiring more identification space, larger flag sizes provide room for detailed labels, serial numbers, and barcode stickers.
Select Pack Quantity
The SBS-MKT range is available in sample, contractor, and bulk pack formats to suit different project sizes. Wholesale quantities and OEM packaging options are also available for distributors and high-volume users.

Frequently Asked Questions — Security Cable Ties & Secure Cable Ties
Seven questions from electrical contractors, security integrators, facility managers, and wholesale distributors. Contact us directly if yours is not listed.
Q1: What are security cable ties used for?
Security cable ties — also called security zip ties, tamper evident cable ties, or security seals — are used wherever a cable bundle needs to be both physically secured and identifiable. Electricians use them to label circuit conductors and phase bundles in panel wiring, writing the circuit reference directly on the flag head with an oil pen. Security and fire alarm system integrators use them to mark and seal cable runs so that any interference with the wiring is immediately visible during inspection. Facility managers and asset tracking teams use them to apply cable asset codes, installation dates, and serial numbers directly to the cable tie rather than using a separate adhesive label that can fall off or be removed without trace. The self-locking ratchet means the tie cannot be opened without cutting — and a cut tie is immediately visible to any engineer or auditor checking the installation.
Q2: How does the writable flag head work on security ties?
The flag head is an extended flat panel moulded as an integral part of the cable tie head. It provides a clean, smooth writing surface that accepts an oil pen or permanent marker without bleeding or smearing. You write directly on the flag area — circuit ID, serial number, asset code, inspector initials, installation date, or any reference text you need to record. The written information stays permanently on the tie throughout its service life and does not degrade under normal industrial conditions. Two flag orientations are available: horizontal (flat and parallel to the cable run, for easy scanning along cable trays) and tall vertical (upright and perpendicular, for dense panel wiring where horizontal flags would be obscured by adjacent bundles).
Q3: What is the difference between the horizontal flag and tall vertical flag cable tie?
The difference is orientation and the resulting visibility in different installation environments. The horizontal flag cable tie (SBS-100MKT, SBS-205MKT, SBS-200MKT) has the writable panel running flat and parallel to the cable direction — this is the most readable orientation when inspecting cable trays, open panels, and cable management racks from the front or side. The tall vertical flag cable tie (SBS-110MKT) has the writable panel standing upright and perpendicular to the cable — this is the correct choice for dense panel wiring where cables run closely together and a horizontal flag would be pushed flat against adjacent bundles and become unreadable. Both designs use the same Nylon 66, UL 94V-2 nylon cable tie construction with the same self-locking seal mechanism. The choice of flag orientation is purely about which direction your installation will be read and maintained.
Q4: What sizes do your security zip ties come in?
Our security cable ties are available in four standard sizes in the SBS-MKT series. SBS-100MKT: 4 inch / 100mm, 2.5mm wide, 18 lbs / 8 kg tensile, bundles up to 22mm, horizontal flag 25×8mm. SBS-110MKT: 4 1/3 inch / 110mm, 2.5mm wide, 18 lbs / 8 kg tensile, bundles up to 22mm, tall vertical flag 21×10mm. SBS-205MKT: 8 inch / 205mm, 3.6mm wide, 40 lbs / 18 kg tensile, bundles up to 50mm, horizontal flag 25×13mm. SBS-200MKT: 8 inch / 200mm, 4.6mm wide, 50 lbs / 22 kg tensile, bundles up to 50mm, horizontal flag 65×50mm — the widest flag area in the range, suited for full asset tag information. Standard packing: 100 pack for the 4-inch sizes, 50 pack for the 8-inch sizes.
Q5: Are tamper proof cable ties suitable for outdoor use?
Our SBS-MKT security cable ties are manufactured from Nylon 66, which provides good outdoor performance in most standard environments. The operating temperature range of -25°C to +85°C covers the majority of outdoor electrical and industrial installation conditions. For installations with prolonged direct UV exposure — outdoor cable management systems, solar installations, external security camera wiring, rooftop electrical runs — standard Nylon 66 will degrade and lose colour legibility on the flag area over 12 to 18 months of continuous sun. For those applications, contact us to discuss a UV-stabilised grade for the SBS-MKT series. For indoor, sheltered outdoor, and standard industrial environments, the standard Nylon 66 construction is the correct specification.
Q6: Can I order security cable ties in bulk for wholesale or distribution?
Yes. Shangbo Plastic supplies security cable ties and security zip ties in bulk directly from our factory in Bozhou, China to electrical wholesalers, security system distributors, cable management specialists, and OEM kit assemblers. Standard packing is 100 pack for SBS-100MKT and SBS-110MKT, and 50 pack for SBS-205MKT and SBS-200MKT. Bulk carton quantities are available for distribution accounts. We also supply 10 pack formats for retail and small-project use. For mixed-size orders across the SBS-MKT range, we accommodate this on a single purchase order. Request a quote and we respond with factory-direct pricing and stock confirmation within 24 hours.
Q7: Do you offer custom colours and OEM packaging for security ties?
Yes. We offer multiple colors for the SBS-MKT series — standard white and blue are held in stock, and custom colours are available for OEM and volume accounts. Colour-coded security systems use different tie colours to identify different zones, inspection periods, security clearance levels, or installation teams — a system that only works when the colour is consistent across batches. We produce a physical colour sample for your approval before any production run starts. For OEM and private label accounts, we supply custom polybag printing with your logo and part numbers, retail blister card, and bulk carton labelling. Minimum order quantities for custom colour and custom packaging are confirmed at quotation stage.
