Why Choose a Mach II 5″ Portable Gutter Machine?

New Tech Machinery (NTM) began designing the Mach II 5″ portable seamless gutter machine in 1991 and shipped the very first unit in 1994. More than three decades later, this portable roll-former is still a go-to for contractors who need to run 5″ K-style seamless gutters on-site.

Uses of 5” K-Style Gutters

If you’re thinking about purchasing a 5” gutter machine, then you’re probably familiar with the market demand in your area. A 5” K-style gutter isn’t ideal for regions with heavy rain or severe storms. That said, they may be more than adequate for homes in moderate to dry climates.

Key Considerations:

  • Roof plane: A 5” gutter usually accommodates roofs 600-800 sq. ft. Larger roofs will have greater run-off and require a larger gutter, like the 6” that holds about 40% more water.
  • Roof pitch: If it’s a small roof with a high pitch, the water will run off faster than a 5” gutter can handle. So even if the roof is the right size for a 5” gutter, make sure the pitch height matches the gutter’s capacity.
  • Climate: In a dry climate, a 5” gutter is fine for any size roof. However, even an occasional strong storm can damage landscape if the gutters overflow, so it’s better to stick with what the gutter can handle based on the roof’s plane and pitch.
  • Appearance: If the house has a wide fascia board, say 1” x 10”, the 5” gutter will look small, like it doesn’t quite fit, but will look fine with a 1” x 6” fascia.

It all comes down to those simple factors. If price is an issue for the customer, keep in mind that 5” gutters require less material, reducing the cost by about 20%.

NTM’s Mach II Portable Gutter Machine

The Mach II 5” Portable Seamless Gutter Machine was the first on the market to offer separate drive and forming rollers. The original prototype featured polyurethane drive rollers, now standard on most portable rollforming machines. Over 30 years ago, when NTM introduced the Mach II, the brainchild of Metal Construction hall-of-famer Ron Schell, nobody had manufactured a machine like it.

The first Mach II, a 5”, returned to New Tech after 30 years in the field. Somewhat worse for wear, it’s now on display in the service department’s lobby. Even after all this time, it’ll still run a perfect gutter.

Add-on accessories

Having the right accessories can make your operation more efficient. Knowing the difference in capacity between a cradle (weight up to 400 lbs.) and a reel (weight up to 1,000 lbs.) may be important when it comes to the size of the job.

Listed below are popular accessories. For a full list, click here.

  • EZ-Counter Computerized Length Controller—Program up to 50 lengths, track material, offer miter options on all gutter machines, operate in feet and inches, inches only, or millimeters, and operate as an Easy-touch screen.
  • Hook assembly – hems the back flange for hidden hangers
  • Bottom-bead assembly – two decorative ribs down the gutter floor (also helps reduce oil-canning)
  • Run-out stands – essential for supporting long gutter sections as they exit the machine
  • Transfer racks—Transfer racks are a great accessory for your gutter machine if you’re using reels. They make transferring loaded coils from one turnstile reel stand to another easier and faster.
