These ductwork prep machines automatically follow any edge –curved or straight. Use the convenient table slot to turn up a “starting flange” and let it go! A calibrated dial can be set for radii as small as 3-1/4” (or 2” when auto-guide is de-activated). Automatically flange 16 to 24 gauge material at speeds of 18 fpm. A non-releasing type head is suitable for open-end fittings, straight and irregular curves. Standard with Lockformer® quality construction, this machine has a motor, and an arc-welded steel stand protected with Lockformer’s top-quality primer and paint finish. The Auto-Guide Flanging Machine is covered by the standard limited warranty described in detail in the Seller’s terms and conditions of sale for a period of six (6) months.
