Strikermatic
The Strikermatic is Powered by a 20 volt Dewalt rechargeable battery (included). The battery charge should last several days but definitely good for a single day no matter the usage. The machines electric cycles allow the user to have some control over the intervals at which the top blade and bottom die come together, a bit like a battery powered drill. The foot pedal allows the operator to hold each edge of a cheek and has a max height of 30”.
Square Framed Access Doors: Dovetail Tabbed vs Press On Self Stick
Square Framed Access Doors are most commonly the Dovetail Tabbed type with a Cam on either side or a Cam and Hinge on either side.
The Increased use of Spiral Flanges (and the decreased use of Slip Couplings) for Job Site speed
Rolled Carbon Steel Prepunched Angle Iron Rings are used in joining ductwork together. Conklin stocks diameters ranging from 3" to 59", manufactured by Midwest Metal Products. Larger sizes, as well as Galvanized, Aluminum, and Stainless Steel Rings, are also available with very short lead times.
Slip & Drive Duct Installation
Slip and Drive Duct is the most common type of rectangular ductwork. Even the largest Duct fab shops will tell you that Slip and Drive duct accounts for a greater percentage than the TDC/F and Ductmate flanged duct they produce.
Buttonlock Machine
Snaplock Buttonpunch on Rectangular Duct is making a comeback! Even though Snaplock has been a SMACNA standard for the Longitudinal Seam on Low Pressure Duct since 1969, many shops left it behind in favor one method- Pittsburgh-that covers all duct pressure classes, thereby streamlining their operation with one method on the longitudinal seam as well as saving money and floorspace from having to buy another machine. Buttonlock and Pittsburgh are run on separate machines.
Ovalizer — Oval Spiral Pipe Machine
Oval allows an for “equivalent round” of a spiral pipe diameter in specs where ceiling height is a factor. Spiral Helix offers an Ovalizer (also known as an Oval Spiral Pipe Machine) to manufacture oval ductwork. The ovalizer takes existing spiral pipe and stretches the major axis (horizontal).
Male Pitts: the often neglected other profile in the Pittsburgh Lock
The Pittsburgh Lock consists of two profiles: the Female and the Male. Yet the Pittsburgh Machines run only one of those as standard: the Female. For decades the Male Pitts has been offered as an optional set for the outboard side of a 20 ga Standard Pitts but no one has ever bought mainly because the standard Pitts runs at a slow 25 ft per minute, so slow that it was faster to take the duct to the Hand Brake to turn the Right Angle Flange.
Plasma Feeders
While Plasma Tables greatly reduce the amount of drop in Duct Shops, Plasma Feeders reduce that even further
ECONOflange and Accuflange Compared
Conklin stocks 10″ thru 36″ ECONOflanges for single wall spiral pipe.
Cradle Caddy and Shear for Flexible Duct Connector
The Cradle Caddy keeps up to three rolls of Flexible Duct Connector or Vane Rail within easy reach, anywhere in the shop. Full swivel casters make movement around the shop possible, and ball bearing rollers quickly dispense connector with a simple pull. A foot actuated brake locks the Cradle Caddy in place when dispensing the connector. The shear attachment cuts the duct connector accurately and effortlessly.
Coil Lines for Rectangular Duct vs. for Precision Blanking/Processing
In a typical commercial job, the Rectangular Duct is comprised of 75% straight duct runs with the remaining 25% being Fittings (basically anything that’s not a 5 ft straight section of ductwork—from Offsets to Elbows to reducers). That 75% translates to a tremendous amount of effort. The machines made by IPI, Engel, and Vicon are made specifically for the fabrication of 5 ft sections of Straight Duct, thus automating the fabrication of Rectangular Duct Sections and addressing t...
