Sioux Chief 3 inch PVC Smart Saddle DWV Saddle Tee Fitting. Schedule 40 trunk with stainless steel bands, 1-1/2 inch hub x 2 inch spigot inlet branch. For adding a tee to plastic or cast iron pipe. Compact design is perfect when DWV stacks are close to walls or other obstructions. Stainless steel bands take up less room than V-bolts or U-bolts and provide even torque, eliminating stress points which can damage pipe and create a poor seal.
