As a manufacturer, Langdon has built a reputation of knowledge and integrity. Our engineering and estimating departments work on all size projects. We have the ability to design and engineer unique, custom applications based on customer specifications. in such cases, Langdon researches the product and makes recommendation concerning any problems that may arise. Langdon has patented ductwork connections and manufacturing processes and has component parts, such products as Sure Seal Spiral a self-sealing spiral ductwork system. Another new innovative product is Sure Clamp Spiral a clamp together spiral system. Langdon has recently developed Sure Clamp Access (patent pending), a removable duct section. With new fire damper inspection requirements proper access to dampers create further challenges. It is next to impossible to properly maintain fire dampers unless you have adequate access to them, working through a small access door causes a poor quality inspection. With Sure Clamp Access a technician is able to properly inspect fire dampers for mandatory requirements while taking less time to make these inspections. This removable duct section allows the technician to comply with maintenance requirements. Products like these are testaments to Langdon's commitment to providing the highest quality products. Landon, Inc. has developed this web site containing pictures of fabricated ductwork, fittings and specialty items. If for any reason the items you need are not shown, please fax us your drawing or call. By making you aware of all the areas which we perform work in, we hope that this will qualify Langdon to bid on your project. Call us Today for a Free Quote!!! COPYRIGHT © 2001-2022 Langdon, Inc.
