7 inch chimney pipe "strap or band" clamp needed

PostBy: zink442 On: Tue Oct 27, 2009 7:50 pm

I am looking for a strap clamp to connect 2 sections of 7 inch pipe. I have a 7inch output on my stove and the 90 degree elbow (7 inch) that comes out of the thimble in the wall and is only about 1 inch above the stove connection. I have to try to slide the stove in while guiding the elbow into the thimble, not fun! I would like to find some kind of "strap or band" clamp that wraps around the bottom of the elbow and the top of the stove output that will tighten up with a few bolts and be air tight. The pipe is 7 inch and the clamp needs to be the same. I do not have the room to pull the elbow out and up for cleaning so this would allow me to disconnect the elbow seperately. Anybody know where to find one? This link looks something like what I need just heavier duty or stainless, I would like to have the seam overlap each other http://www.efireplacestore.com/cpf-73798.html . If you have any other ideas I would like to hear them also. Thanks

My Dad's trick was to put the stove up on bricks. Get everything lined up & the bricks exactly remove the slack.

I think that you might be able to use the kind of strapping that is used to bind antennae "hold-offs" to masonry chimneys...Anyone selling Antennas should have them.
Otherwise you might find them in a plumbing supply or roofing supply I have seen large hose clamps on commercial roof drain pipes...Then you might buy from MSC supply if you wait a day or two:

What's wrong with cutting a strip of sheet metal to the dimensions you need? Bend up the ends to take one or two nuts and bolts with a small piece of sheet metal to slip inside the area not covered under the bolts. Should still secure with sheet metal screws though. You could cut the strip from a piece of 7 inch smoke pipe; after bending up the ends for bolts it would leave a 1 inch gap under the bolts to cover with a small piece of the same material.

Don't depend on the clamp to secure the pipe, three screws each end.

I think Franco is on to something. I was thinking about getting a long strap and having some angle welded on both ends to run some bolts thru. I was going to have one angle spot welded about 2 inches back from the edge to have the overlap for sealing the joint. The screws are also a good back up. I thought I saw someplace selling heavy duty clamps that were like a strap but I could not find them again. Thanks! I will let you know how I make out.

http://www.chimneylinerdepot.com/ is local in Pa and will custom make anything you want and are reasonable. They have made a few custom pieces for me out of stainless and excellent. I just give them a call and email or fax them a drawing of what I want and they price it up.

I just made a 4 inch band strap for hanging a temporary stove pipe. Took a piece of sheet metal, rolled it into a round shape, and put a 1 inch bend in each end, in order to screw the two ends together.
