Gray Yard Drain Emitter - Angled Grate Yard Drain Design for Sump Pump Discharge & Downspout Extensions - Protect Home Foundation, Prevent Stagnant Water - Fits 4" Drain Pipes - Heavy Duty Lawn Grate

Product is extremely well built. Stainless plate is a little rough around edges but a little file touch up went a long way. I was very happy with this product and will be using again for drainage.

Exactly as described, maybe better. Stainless steel grate. Wish had it sooner.

Mine are super heavy duty black plastic 4 inch pipe with STAINLESS STEEL grates, that look to be a 16th of an inch or so, which is very stout. The week link is that the grate is only held by the two screws in the pipe, but I'm super happy about the SS. I have no idea why they said 'grey.'
