Here at Bootstrap Farmer, we carry three distinct styles of lock channel to suit your greenhouse building needs. Our entire selection of lock channel is made in the USA from recycled aluminum. It’s strong enough to last for years while being flexible enough to follow the curve up and over your end wall hoops. All channels are 6.5-foot long and include free shipping.
Deep Greenhouse Lock Channel is perfect for light dep. structures and any structure with a double layer of woven poly. It holds six layers of spring wire and up to 40 mil. of material. The available bundle comes with two sets of spring wire per length of the channel.
Double Greenhouse Lock Channel is designed to make it easy for you to have different coverings for your sidewalls and easily change them out depending on your needs for the season. Each channel can hold as much as the classic U Lock for a total of six layers.
Spring Wire can be ordered separately for each additional layer of material you plan to use.
