About the EERA T40 Trapezoidal Flashing Notcher

The EERA T40 Trapezoidal Flashing Notcher cuts rib notches in flashings and trims for the T40 trapezoidal profile. The notch is 40mm high, 70mm across the base and 23mm across the top, sized so the flashing sits down over each rib. EERA designs and manufactures the tool in Warrnambool, Victoria.

Notching a long flashing with snips means measuring, marking and cutting both sides of every rib. The notcher, also called a flashing cutter or flashing puncher, does each one with a single pull of the lever. Its head is shaped to the T40 rib and finds its own position, so the spacing takes care of itself.

The tool suits roof plumbers, sheet metal shops and builders who flash T40 roofs often enough that marking out by hand has become the slow part of the job.

Folding Before You Notch

EERA recommends folding T40 flashing or trim to 90 degrees on a sheet metal folder, 40mm long. The turndown then matches the rib height. Fold the full run first, set the edge in the notcher, let the head seat over the rib and pull the lever. Move along to the next rib and repeat.

What You Need to Complete the Job

Frequently Asked Questions

Can I order replacement blades for the T40 notcher?

Yes. T40 Trapezoidal is one of the six profiles with replacement blade sets listed online. Open the EERA replacement blades product and choose T40 Trapezoidal from the Suits Notcher option. Each set fits one notcher only, so check you have selected T40 before checkout.

What is the difference between the T40 and BTD 45 notchers?

The rib size. The T40 notch is 40mm high, 70mm at the base and 23mm at the top. The BTD 45 notch is 45mm high, 75mm at the base and 22mm at the top. EERA blades are not interchangeable, so measure the rib on your sheet and choose the matching tool.

How thick a flashing will it cut?

EERA rates the T40 notcher for galvanised steel up to 1mm and prepainted steel up to 1mm, with a cutting tolerance of plus or minus 0.5mm. It works by manual lever, so there is nothing to plug in on the roof. It is not designed to cut hips.

Is the T40 notcher made in Australia?

Yes. EERA designs and manufactures it in Warrnambool, Victoria. It has a powder coated handle and high strength hardened steel blades. When the blades wear, they can be sharpened, or replaced with a T40 set from the EERA replacement blades listing.
