The Microfiltration Continuous Hanger DoublePro in 8 questions.

1.What’s the purpose of the second layer?

A: The second layer blocks debris like pine needles that can clog the gutters while letting through debris like pollen and sap that could otherwise clog the gutter guard itself.

2.Are the perforations smaller than the T-Rex Continuous Hanger?

A: No, they’re the exact same size. You look thinner when you wear black—it’s the same visual effect for perforations on a black product.

3.Does this product have fewer perforations than the T-Rex Continuous Hanger?

A: No, we simply combine two perforation lines into one, so there are more holes on one line and a larger gap between perforation lines.

4.Does this product drain enough water?

A: It drains the same amount of water as the current T-Rex Continuous Hanger which is to say 29.7″/hour—more than twice the highest recorded rainfall (12.3″/hour). Since the second layer has a larger open surface, it doesn’t reduce the overall intake.

5.Will there be clogging between the two layers?

A: No. The second layer is only meant to block direct access to some debris like pine needles and is designed to be continuously washed by rainfall. The space between holes is small enough to prevent dirt from piling up.

6.Will snow and ice build up between the layers?

A: Although a thin layer of ice is possible on the second layer, the large holes will prevent any major buildup in between. Tested in a freezer in different buildup conditions (all at once and progressive freezing) and through two full winters in Canada, the two layers always kept their shape.

7.Is this product over-designed?

A: The dual-action system may seem complex, but it’s fairly simple to understand: the Alu-Rex design team found that a system with two layers of aluminum was the most maintenance-reducing system that could be manufactured. The DoublePro reduces gutter clogging to a minimum and also minimizes guard clogging by letting debris normally evacuated by the gutter system move through its porous membranes.

8.Is this product better than micromesh gutter guards?

A: Short answer: Yes!

The main challenge with micromesh gutter guards is the mix of pollen, sap, asphalt shingle granules, and pollution that clogs the micromesh itself. Most micromesh manufacturers sell or provide a brush to use to get rid of these substances so they don’t stop water from passing through the micromesh. The warranty even warns you that you might need solvent to dissolve tough debris.

The DoublePro design minimizes guard clogging by letting sap, pollen and other micro-debris normally evacuated by the gutter system move through the two layers. It’s the perfect balance between microfiltration and water drainage.
