These handy wire hoops allow you to quickly assemble a small protective tunnel for your plants. Wire hoops measure 16" wide by 23" tall, but are flexible enough to be widened at the bottom if needed. Simply wrap twine around each loop and move up to the next hoop and repeat. Twine provides support between plants to prevent sagging and the cover coming into contact with plants. These loop hoops can be spaced up to 10' apart in the row. Hoops are made from 6 gauge galvanized metal.
