12½ inch Branch

This page collects every 45° cut-in pipe saddle with a 12½ inch branch outlet, to suit main duct diameters from 12½ inch to 40 inch (13 sizes). The saddle is cut into an existing spiral duct run on site, letting you add a branch at 45° without dismantling the ductwork. Select the fitting sized for the main duct it will sit on, then connect your 12½ inch branch ducting to the outlet. These fittings are made to order and despatched in 3-5 working days, with free UK mainland delivery on orders over £400 ex VAT.
