Signumat Protectors

The protectors represent a simple and ecologically worthwhile measure not only against game browsing, buck rubs and birds, but also against the formation of tree forks. This is possible due to the appropriate geometry and the high-quality, technical plastic. With the stable, tried and tested snap-fastener, the protectors offer a time-effective protection for both – soft- and hardwood. In addition to the UV-resistance of the colors, there is another benefit: the blue color has a deterrent effect on game. The protectors should be placed on the terminal shoot between September and March. Then, a year-round protection is guaranteed. 


The EasyClip was developed – and is proudly manufactured – in South Africa. There was a need for a tough, cost-effective fastening system that saves installation time and allows for easy maintenance while still providing a high-quality finish that extends the lifetime and improves the aesthetics of any hardwood timber or composite deck.


We develop and produce high quality products to improve the accuracy and efficiency of field work. The products are used for many different purposes, especially in forestry. But there are also many other areas outside the forest industry where the products are the solution.


The Signumat system helps you improve both organization and accuracy of stock control.

Made from top quality plastics and materials our products are durable, easy to apply and will save you time! Signumat products have proven quality, don't be fooled by imitations.
