Our Products #5144081

MKT products are factory fabricated to meet or exceed 3rd edition 2005 SMACNA Standards. MKT Standardizes rounded duct typically with USA mill-stamped, G90 galvanized steel*. We not only meet requirements set by the state and federal entities, but our highest standards are held by our own quality control guidelines.*Specific needs and application do applySnap lockEconomical. Shipped knocked-Down and assembled in the field. Typically used for light commercial or multi-family residentialcondosapartments. Easier to take mass quantities to a multi-story job. Normally wrapped in the field for installation. Low pressure work.FlangeConnecting System, 2 different flanges, angle ring flange (Accuflange spiral, commercial HVAC application). Industrial flange (Burkholder)-high heat, high pressure, high velocity.Van Stone FlangesPractical and labor saving method for connecting both industrial duct and pipe. Industrial duct: the Van Stone connection consist of a face flange and a backingflange with a slip fit over the duct. The face flange is mechanically formed from the end of the duct section by turning the edge of the duct and forming a lip with an outside diameter small enough to clear the connect bolts.Double WallDouble wall Solid Inner (only R value) and Double Perf Inner (R value and decibel ratings). 2 different scenarios: Insulate the pipe for an industrial application solid inner. Perf, are wholes in trap sound as well as R Value and decibel ratings.WeldedA fabrication or sculptural process that joins materials. A level beyond HVAC applications to enclose fumes, biologicals, high pressure, particulate.

MKT products are factory fabricated to meet or exceed 3rd edition 2005 SMACNA Standards. MKT standardizes most rectangular duct construction with USA mill-stamped, G90 galvanized steel. We not only meet requirements set by the state and federal entities, but our highest standards are held by our own quality control guidelines.*Specific needs and application do applySnap LockEconomical. Shipped knocked-down and assembled in the field. Typically used for light commercial or multi-family residentialcondosapartments. Easier to take mass quantities to a multi-story job. Normally wrapped in the field for installation. Low pressure work.Slip and DriveAssembled in the field. Typically used for light commercial or multi-family residentialcondosapartments. Size of the duct has a lot to do with where you use slip and drive. Needs to be sealed after installed. Its used in low to medium pressure systems.TDC Flange (Transverse Duct Connections)rectangular-ductworkTDC flange is a roll form flange connection that provides a solid metal connection directly onto the duct reducing air leakage. Typically used for light and heavy commercial. It is quicker to install in the field, more leakage resistant that slip and drive. Uses a 4 bold connector system. The gasket is designed for low, medium and high pressure systems.Double WallA double-walled duct is a secondary contained duct system. It is a duct within a duct, or encased in an outer covering, with an annulus (interstitial space) between the two diameters. The inner duct is the primary or carrier duct and the outer duct is called the secondary or containment duct. Conditioned space, quieting space.WeldedA fabrication or sculptural process that joins materials. Typically used requirements are biological consideration (pharmaceutical), (duct must be sealed) or exhaust requirements, smoke, fumes, dust collection systems.ApplicationRectangular Duct is best used when physical space limitations and high air carrying capacity requirements are tight.Marketable ApplicationsVentilation Systems, HVAC Systems, Dust Collection Ventilation, Heating and Air ConditioningRectangular Duct InstallationDelivered with our product, all supplies come with connecting hardware, including, slips and drives, nutsbolts, gasketed materials and hanging system.All rectangular duct (except Snap Lock) can be lined with fiberglass, closed-cell foam, or any other industry material. On instances where specified, we can also manufacturer double wall duct.

MKT recommends using slip in couplings up to 24 diametersQuick, simple, relatively inexpensiveLight to moderate strength characteristicsRequires sealing in the field if necessary

Simple installation processCan be installed on-siteShop installation has proven to:protect the ends of spiral in transitreduce labor time in the fieldAvailable in 8 to 72 in standard 2 incrementsRequires sealing in the field or the shop if necessary

Self SealingTime and labor savingAdjusts automatically to slight duct diameter variationsOffers inner ring for use with Spiralmate on Double Wall spiral connectionsHas been lab tested to 18 positive WG and 10 negative WG

Typically used in heavy, industrial applicationsLarger diameter and gauge spiralround duct uses angle ringsCan be used in conjunction with van stoning on the round duct for a slip ring capabilityRequires additional gasketing if requiredAvailable in all materials including galvanized, pricing and availability on request
