Stretching easily over the ends of pipes, bamboo poles or any other rigid stake material from 1/4" to 3/4" in diameter, these connectors make it simple to construct your own plant frames and supports. Made of 100% silicone, they hold snugly once positioned and will return to their original shape when removed. They are resistant to the effects of weather and UV rays, and can be reused year after year. Made in USA.
