These shelters feature a strong, open mesh structure that provides protection from browsing animals without altering the microclimate around the tree. The flared top rim prevents stem abrasion and strengthens the tube. Pre-fitted releasable nylon ties allow for fast installation and easy maintenance. Made of recycled plastic, the UV-stabilized shelters typically last a minimum of 5 years and will split to prevent strangulation as the tree grows. Pack of 4.
