Customer Questions & Answers

Can i buy striping material longer than 12 feet my chimney is 22 feet in diameter brick

Asked by: walter
Go to a plumbing supply and buy some strapping for supporting pipes. I am not sure if it will be as thick as whatever the antenna mount comes with. In a good plumbing or industrial supply house you can also find copper strapping. It will hold up well, but tend to stretch with temperature changes. Both materials come in rolls of several feet. Whatever you use, you can always increase the length by bolting an additional length onto it. If there is a strength or durability question you can also double up thinner material and zinc prime and paint it.

How do I apply the strapping seals?

When applying the strapping seals, do I need any special tool? Or a simple pliers would do the trick.
Asked by: John
Installing the chimney support can be done by using no tools - BUT, it's so much easier with pliers and a thick neck screwdriver. The screwdriver with a long thick neck is just the thing for turning the twist adjustment bands. A picture of how to install and what these support bands should look like on your chimney is below. This installation requires a bit of patience. Just be very careful up on the roof and keep your attention span focused on the job at hand. The screws, washers and nuts should be tucked into a shirt pocket for easy griping when needed. Drop one of these tiny things and if your luck is like mine, they'll do a drum roll right into the gutters IF you're lucky. I dropped a nut and it bounced off the rim of my gutter and into a pile of leaves below.

Initially i wanted to use the J pipe antenna mount but i'd have to drill few holes into my chimney. Then i found this! I was glad that this require no holes at all into my chimney. You just wrap it around the chimney and it was pretty sturdy. You need to go to the channel master to get the instructions though as the package does not come with the installation instructions!
