Stretch-Lock Installs Fast Easy Two Ways! The Stretch-Lock tying system does double duty in the field. Its locking head fastens securely and its cushioned texture is soft on plant stems. Together, they offer superior flexibility to secure and train young trees vines. Stretch-Lock can be used as a "Single-Wrap" to simply secure a stem directly to a stake. Where abrasion is a concern, Stretch-Lock can be installed in the "Loop-Through" method to create a rubber buffer between the stem and the stake. Choose the installation option below that's right for your plants. Note: Stakes shown in images are Plantra's Patented Trunk-Builder Fiberglass Support Stakes. Stretch-Lock will also work with other stake materials including bamboo, wood and metal. Single-Wrap Method This method is used to secure plant stems directly to a stake. To install, simply wrap Stretch-Lock around both stem and stake and secure - see diagram to right. If extra length remains after installation, make one more wrap around stake but not the stem. Loop-Through-Method This method is used to secure plant stems with a soft, protective buffer between stem and stake. To install, wrap Stretch-Lock in a "figure-8" double loop as shown in diagrams to right and below. Start with a single wrap around the stem - avoid wrapping stems more than once. Next, thread Stretch-Lock head through the opposite end and wrap around stake. If extra length remains after installation, make one more wrap around stake but not the stem.
