DuraVent DuraTech LDC Elbow Strap: support for the slanted pipe between elbows
The DuraVent DuraTech LDC Elbow Strap is a support band and strap for the slanted chimney pipe between two elbows. It carries that weight instead of leaving it on the elbows. DuraVent requires a strap for each pipe length in every offset, where the chimney changes direction. Straps are sold separately from elbows. The band clamps around the upper elbow, and the strap attaches to a joist or rafter with nails or screws. Support the elbows before adding more pipe. DuraTech LDC is DuraVent’s large diameter chimney, an insulated double wall pipe made in 10 to 24 inch sizes for big fireplaces, furnaces, and boilers.
Choose the diameter that matches your chimney, from 10 to 24 inches in 2 inch steps. Use only DuraTech LDC parts, not 5 to 8 inch DuraTech, DuraChimney II, or another brand. A chimney allows one offset using two 15 or 30 degree elbows, never steeper. At most, half its length can be slanted, with elbow straps supporting it. A straight chimney draws smoke better.

The DuraVent DuraTech LDC Elbow Strap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
