The McElroy Sidewinder fusion machines give you the ability to saddle fuse 4" IPS and smaller branch saddles, tapping tees and service saddle fittings onto 1 ¼" to 4" IPS main sizes. The Sidewinder is available in two configurations: Jaw Clamp or Chain Clamp. The Jaw Clamp Sidewinder is used for fusing branch saddles, tapping tees and service saddle fittings onto 1¼' to 4' IPS main sizes. The Chain Clamp Sidewinder gives you the ability to fuse onto main sizes larger than 4" IPS. Both Sidewinders are DataLogger^® compatible.
