When you build a greenhouse, you’re making an investment in your future as a commercial or hobbyist farmer. Using this durable and affordable lock channel in that greenhouse’s construction will ensure that it lasts for years to come in even the harshest environments. What’s more, this lock channel for spring wire (also known as wiggle wire) can help prevent greenhouse plastic tearing that commonly occurs during or after greenhouse installation, which is but one of the many ways in which they help to protect your investment. The flexibility of this lock channel allows you to bend the channel around the arches of your hoop house.  The aluminum allows for easy pre-drilling or use of self-tapping screws which makes installation a breeze.  Once your greenhouse is constructed, you can rest easy knowing that the aluminum alloys will keep your lock channel from rusting or decaying over time.

If this is your first time making use of a lock channel, please be sure to watch the videos below for a demonstration on how easy they make adding and removed your greenhouse covering. Please be sure to also add a spring wire (wiggle wire) to your order, as it is not included with this item.

    Ask a Question
    • The lock channel is advertised as rust-free. Would it be safe to attach to pressure treated wood?

      If you are using pressure treated wood we would recommend putting a strip of plastic or building wrap tape between the wood and lock channel.  The copper in some pressure treated woods will corrode anything metallic that is not stainless steel or copper (this would include almost all greenhouse attachment methods).  However in most cases pressure treated wood should not be necessary on your greenhouse unless the wood it is in contact with the ground.

    • How do u cut the channel?

      The greenhouse u channel can be cut using a hacksaw or any other saw or other saw blade that is made for cutting metal.

    • Is this channel capable of holding two sets of spring wire, ie one holding two layers of plastic and one holding the shade cloth?

      Yes you can use it with one or two sets of spring wire.
