On chilled-water and cryogenic lines it keeps the handle above the frost zone, so the grip stays dry and the operator&#8217;s hand stays off the freezing surface.<\/p>\n<h3>Do I have to cut the insulation to fit it?<\/h3>\n<p>No large openings are needed. The point of the extension is to keep the insulation jacket intact \u2014 the handle simply sits above it.<\/p>\n<h3>\u4fa1\u683c\u3092\u78ba\u8a8d\u3059\u308b\u306b\u306f\u3069\u3046\u3059\u308c\u3070\u3088\u3044\u3067\u3059\u304b\uff1f<\/h3>\n<p>Send us the quantity, the extension height you need, and the valve model it is for.
