Both compact and economical, this Metal-Fab Type B Round 90-Degree Adjustable Chimney Elbow is ideal for any homeowner who literally wants the most for the least. An advanced dual-wall construction allows this vent pipe elbow to be very efficient without taking up a lot of space. It also requires just a single inch of clearance to combustible materials, giving you quite a bit of installation flexibility even if you've got a smaller home.
Another unique feature of this Metal-Fab Type B Round 90-Degree Adjustable Chimney Elbow is its innovative SureLock locking system. This patented system makes creating a secure vent connection as simple as putting two components together, twisting, and pushing a button. There's no need for tools and it's completely impossible for the pieces to accidentally twist apart.
And, perhaps even more impressively, this Metal-Fab Type B Round 90-Degree Adjustable Chimney Elbow Length is compatible with a variety of other brands of vent pipe. Without requiring a hard-to-find specialty adaptor. That means that you can connect it to an existing common vent rather than have to do an expensive remodel or create an entirely new vent line. All in all, you won't find a more convenient and cost-effective way to vent your gas appliance than with a Metal-Fab Type B chimney.
