Security Fence Spikes: The Complete Guide to Security Toppings

In today’s security landscape, perimeter protection needs to do more than mark a boundary; it must actively deter intrusion. For commercial and industrial sites and in some cases residential gardens, fence spikes, also known as security toppings, provide a highly effective solution for preventing unauthorised access while reinforcing the integrity of your fencing system.

At Jacksons, our professional grade range of security toppings are engineered to deliver robust protection, combining durability, compliance, and visual deterrence.

What Are Security Fence Spikes?

Fence spikes are specialist security toppings installed along the top of fencing systems to prevent climbing and unauthorised entry. Unlike standard residential deterrents, specialised commercial systems are specifically designed to withstand high risk conditions and deliver long-term performance.

They are manufactured using high quality materials such as stainless and galvanised steel, which offer exceptional strength, corrosion resistance, and reliability, making them ideal for high security sites, utilities, data centres, industrial estates, schools, warehouses, and other critical infrastructure sites.

Why Fence Spikes are Essential for Fence Security

Security toppings such as fence spikes play a critical role in layered perimeter defence strategies. When combined with high quality fencing and secure installation, they significantly reduce vulnerability to intrusion.

Key advantages:

  • Strong visual deterrent to prevent attempted access
  • Difficult-to-climb barriers for enhanced protection
  • Long lifespan with minimal maintenance
  • Some are suitable for retrofitting onto existing fencing
  • Types of Fence Spikes (Security Toppings)

    Jacksons offers a comprehensive range of advanced spike systems, each suited to different requirements.

    Security Comb

    A widely used commercial solution, Security Comb is an entry-level security spike topping featuring rigid teeth that create a consistent anti-climb barrier. It’s effective, discreet, and cost-efficient. Easy to install on a variety of surfaces, it can be used in residential gardens and a variety of applications.

    Cobra Spike

    Cobra Spike, also known as Razor Spike, delivers continuous spike coverage along 1.5m with 110m spikes. It’s the next level up from Security Comb with its menacing teeth and is ideal for commercial environments where both security and presentation matter. Due to its flat base, it can be retrofitted to fences, gates, or walls.

    Cobra Spike Rotary

    Cobra Spike Rotary adds a rotating element to the original design, preventing grip and making climbing extremely difficult; made up of two lengths of modified Cobra Spike affixed to a galvanised tube. Ideal for sites requiring enhanced deterrence for high security sensitive installations, the free rotation provides an unstable barrier that is difficult to climb and dangerous to negotiate.

    Rota Spike

    Rota Spike is a rotating spike system with large triangular spikes that rotate, making it virtually impossible to climb over, providing a psychological and physical deterrent for high risk perimeters. It is supplied in 6m lengths and can be utilised on buildings to protect vulnerable points like windows and roof parapets.

    Viper Spike & Viper Spike 3

    Designed to form a more imposing three dimensional barrier than barbed wire, the spikes offer a strong deterrent to climbing. Viper Spike and Viper Spike 3 offer aggressive deterrence, making them ideal for industrial and infrastructure security. Viper Spike can be installed on any flat top fence, and Viper Spike 3 is designed to prevent intruders from climbing drainpipes or other vertical structures.

    Barbed Wire and Barbed Tape Fence Topping

    A traditional, less rigid security topping option, barbed tape and wire systems provide a highly visible and formidable security topping, commonly used in high security applications. They further enhance perimeter security across different applications, whether as a fence and gate topping or in drop zones. A range of galvanised barbed tape and wire is available, including concertina razor wire, barbed wire rolls, and flat barbed tape.

    Note: We recommend that all spikes be attached to walls and fences at a minimum height of 2.5m with adequate warning signs.

    Warning signs for fence spikes
    We recommend ‘Danger/Warning Signs’ be used every 8-10m along a fence line that incorporates any security extras capable of causing injury, even through misuse.

    Compliance: Can You Put Spikes on Your Fence in the UK?

    For commercial properties, installing fence spikes is generally permitted, but businesses must meet legal and safety obligations.

    Key considerations:

  • Duty of care: Security toppings must not present an unreasonable risk
  • Placement: Spikes should typically be installed above head height
  • Visibility: Systems should be clearly visible and not concealed, with appropriate warning/danger signs
  • Intent: Designed to deter, not to cause harm
  • Common questions:

  • Can you put spikes on your fence?
    Yes, particularly in commercial environments where security is required.
  • Can I put spikes on my fence UK?
    Yes, provided installation follows safety guidance and duty of care principles.
  • Is it legal to put spikes on your fence UK?
    Yes, but only if they are used responsibly and appropriately. With adequate signage.
  • What About Fence Spikes for Cats?

    While security toppings are designed for intrusion prevention, residential alternatives, such as fence spikes for cats, are also readily available. These are typically softer and designed to deter animals humanely. It’s important not to confuse these with commercial-grade systems, which are purpose-built for security applications.

    Choosing the Right Security Toppings

    The right fence spikes will depend on your risk level, site type, and operational needs.

    Consider:

  • Risk level (low, medium, high security)
  • Type of site (commercial, industrial, infrastructure, high security)
  • Required deterrent level (visual vs physical)
  • Material durability (e.g. galvanised steel)
  • Integration with existing fencing systems
  • Typical recommendations:

  • Commercial premises → Cobra Spike or Security Comb
  • Industrial sites → Viper Spike or Rota Spike
  • High security environments → Barbed tape and wire or rotating variants of the above

    Strengthen Your Perimeter with Fence Spikes

    For businesses looking to enhance their perimeter security, fence spikes remain one of the most effective and scalable solutions. Whether upgrading existing fencing or designing a new system, choosing the right security toppings is key to protecting your site.

    By investing in high quality fence spikes and advanced topping systems, you can create a professional, compliant, and highly secure boundary, built to deter and designed to last.

    While fence spikes and security toppings are highly effective, they should never be the only line of defence or a singular deterrent against climbing. The foundation of any secure perimeter is the fence itself, its height, materials, and design. Features such as small mesh apertures, vertical bar designs with minimal footholds, and specification of adequate fence height make climbing inherently difficult before any toppings are added. Security toppings, such as fence spikes, should then be used to enhance this primary barrier, serving as a secondary deterrent rather than the sole solution.

    For the most effective results, always take a layered security approach: starting with a correctly specified fence, supported by high quality toppings such as Cobra Spike, Viper Spike, or barbed tape where appropriate.

    By combining a well designed anti-climb fence with professional high quality security toppings, you create a robust, compliant, and highly effective perimeter security solution.
