This post covers another one of our most frequently asked questions, and we hope the description and video can help clarify this issue a bit more. Thanks for your feedback!
The beauty of wirelock is its ability to hold multiple layers of covers, even covers in different directions (i.e. roof and ends or 2 long lengths). Before starting you must at least have the cover tacked at the opposite end. This will give you resistance for pulling the cover tight. Our wirelock channel will hold up to 3 layers of 6 mil plastic securely. Two layers of 12 mil tarp will not be held securely in the wirelock channel. This is why we recommend that the top of the end wall tarp be sandwiched between the channel and the hoop.
If you have never installed these covers before, it is recommended to use at least 3 people. After the bottom of the end cover has been secured, pull the end cover over the hoop first. Person “A” will hold it from the inside of the structure in such a way that there are no wrinkles. The roof cover can now go over the channel as well. Person “B” will pull on the roof cover while person “C” installs the stainless spring steel wire inserts. “C” will start from the peak and work down. It is critical to remember that “A” and “B”, who are pulling on the two respective covers, must always be pulling at least a foot ahead of “C” who is installing the wire insert. This will allow a little give in the covers so that there will not be damage. With more experience “B” and “C” can be done by one person.
It is also important to remember the wrist technique for installing the wire insert. Do not slide the wire straight back and forth. This causes abrasions on the cover. As you move back and forth, apply pressure with the thumb on the next parallel spot of the wire insert. Use a needle nose pliers to get the last tip into the channel. The next wire insert does not have to be overlapped.
