15 Degree Stainless Steel Elbow Kit (2 elbows, 1 elbow strap)for 7" DuraPlus Chimney System by Dura Vent

This triple-wall chimney features two insulating layers (ceramic blanket, plus air space). The ceramic blanket insulation is held securely in position, eliminating hot spots common with loose-fill type insulations. In the event of a creosote fire, the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction.

Use for offsets around obstructions such as rafters, ridgepoles, or joists. May have two pairs of elbows, if needed. Offsets greater than 30 degrees are not permitted in accordance to UL 103 standards. Elbow swivel 360 degrees at base (angles are not adjustable). A pair of elbows is required to return an offset chimney back to vertical.
