Protect your trees against all animals from Beavers to Deer and even lawn equipment! These tree guards are 48 inches tall and can be easily bent and trimmed to install around preexisting trees up to 4 inches in diameter. These come with a pack of 40 Zip Ties including everything you need for installation. Both the Tree Protectors and the Zip Ties are UV treated to prevent deterioration by sunlight exposure. The biggest advantage that these protectors have over competing products is the small durable mesh. To be helpful yet not harmful to the tree, a tree protector needs to offer good ventilation and not build up moisture, while still offering enough protection to block animals from chewing or rubbing the bark. Other tree wraps or tubes hold moisture that will harbor insects, disease, and rot. Other mesh tree protectors that have too large of openings still offer vulnerable access to the tree. This is a pack of 5 guards with 40 zip ties.
