Erickson's Re-Tractables are so simple to operate - simply pull the web out to the desired length and start ratcheting until tight. To release, simply push down on the red release button. The web not being used is stored in the center housing so you have no web blowing in the wind. This feature also keeps the straps clean and free from oil and dirt. | Erickson Manufacturing Ltd. 4-Pack 1,500 lb Re-Tractable Tie-Down Straps | Size 1"W x 6'L
