Downspout Armor That Seals Out Pests, Debris & Sharp Edges

GutterGate is the rugged, American-made cap that turns an open downspout into sealed downspout armor — keeping critters, leaves and injury out of your yard.

Open downspouts are an open invitation

The problem GutterGate was built to solve.

Mice, squirrels, snakes and insects crawl up open pipes and into your home.

Leaves and roof debris wash down and clog the outlet, backing up water.

Exposed metal edges cut fingers, scratch kids and slice garden hoses.

The Solution

Armor for your downspout — installed in seconds

  • Durable ASA cap slides onto the end of any standard downspout and secures with the 2 included screws (screwdriver or drill).
  • Seals the opening so pests can't climb up — the hinged door lets water and debris flow through.
  • Smooth, rounded finish removes sharp edges without restricting water flow.
  • Made in the USA and built to last forever — never rusts, never needs replacing.

Downspout Armor — Frequently Asked Questions

What sizes does GutterGate downspout armor fit?

Type A fits standard square 2x3 and 3x4 downspouts, Type B fits rectangular 2x3 and 3x4 downspouts, and our 4" Round cap fits round downspouts. Use a credit card to compare: if the card is bigger than the opening, order 2x3; if it's smaller, order 3x4.

Will downspout armor restrict water flow?

No. GutterGate's hinged door allows full water flow through your downspout while keeping pests out, so your drainage system works exactly as it should.

Is it really made in the USA?

Yes. Every GutterGate is manufactured in the United States from durable ASA and built to last the life of your home.
