These bespoke spiked anti climb collars are also known by several other names including; anti climb brackets, spiked collars, pole collars and anti-climb post collars, among others.

They provide a simple, effective and practical solution to protecting posts (and post mounted equipment) against thieves and vandals.

Posts are often used for mounting items at risk of theft or vandalism such as; security cameras, security lighting, tannoy speakers and other equipment, but posts can also offer burglars or vandals a climbing aid to assist access over a wall or security fence, or onto a flat roof, etc.

Anti climb brackets and spiked anti-climb collars can be used in conjunction with other anti climb products to increase the level of security further, and are for example, often used in conjunction with anti climb paint (also known as anti intruder paint or burglar paint).

Spiked Anti-climb Brackets and Post Collars are manufactured from welded steel components and are galvanised for protection against the weather. If required, they can also be over-painted with a robust baked on powder coat paint finish as an optional extra. The brackets can be painted in any standard RAL colour, with Green and Black being popular choices.

The Insight Security range of anti climb collars and brackets, offer both a visual deterrent and practical physical barrier against would be climbers.

To order your anti-climb brackets you will need to know the diameter of the post, as the collars are manufactured to fit a specific size (diameter) of post. The length of the spikes on square collars is approximately 400mm (16″)
