Protect your customers' trees better with Tree Guard dynamic cabling. This noninvasive tree support system does a better job of supporting trees than steel cable because the system has the ability to flex as the tree moves in wind or under ice and snow. If the system is overloaded, specially designed over-load indicators become visible on the slings used to install it - a vast improvement over static steel cable which can fail without visible warning. Because Tree Guard installation uses slings wrapped around the stems to be supported and spliced rope to connect them, there is no drilling in the tree. This helps preserve the integrity of a marginal tree, and can mean a more successful preservation.
All cabling systems have to be inspected and periodically maintained. Tree Guard is easier to inspect than any other tree support system because of the overload indicators built into the slings which are clearly visible from the ground. These indicators become visible when the system load exceeds 75%. When the customer sees that in their tree, they know it is time to call you. Tree Guard line comes in two different elasticities, either 5% or 20%, which allows cabling systems to be better customized according to the specific needs of the individual tree. Because it uses slings, Tree guard does not place the line around the trunk, which prevents the throat of the eye splice being forced open over time as the tree grows.
More Information and on Tree Guard can be found in the following PDF file which is an extract from the Drayer catalog. (Drayer is the European distributor for this system. Note, in Europe the system is sold under the name “Tree Save”.)
Cabling with Tree Guard is an investment which will quickly pay for itself. We've made it easier to get started using this new system with this startup kit which provides an excellent array of slings and rope to cover the most likely cabling situations.

Tree guard slings should be long enough to lay both eyes easily side by side. The sling length should be 4 times the diameter of the branch. Tree Guard slings are protected by an anti-abrasion cover, and feature overload indicators on the 2, 4, and 8-ton slings.
Tree Guard rope is a 12-strand hollow braid that is easy to splice by hand, making installation quick and easy, and much nicer than working with steel cabling. Tree Guard is available in 3 sizes and strengths. Each size is available in 5% elasticity or 20% elasticity for installations that require more stretch in the system.
14mm Tree Guard Rope has a strength of 20 kN (4,500 lb.) 12-strand hollow braid rope is easily hand-spliced. Sold by the foot.
18mm Tree Guard Rope has a strength of 40 kN (9,000 lb.) 12-strand hollow braid rope is easily hand-spliced. Sold by the foot.
