NDS11, 4 in. Round Grate Cover Connects to 4 Inch Drain Pipes & Fittings, for Small Lawns, Landscaping and Patios, Black Plastic

Look, it’s not glamorous… it’s not exciting… it’s a round black plastic cover. But when you need one, you really need one. I got this to keep rodents, leaves, and who-knows-what from crawling into my 4" drain pipe, and it does exactly that — no complaints from the squirrel union so far.Honestly, I checked every local hardware store, and none of them carried this exact size or type. So instead of doing the “wandering the aisle” dance for the third time, I ordered this one, and boom — problem solved.It snaps right on, fits snug, and hasn’t blown off in a storm (yet). If you’ve got a drain pipe and don’t want a raccoon roommate, this little guy is your new best friend.

Durable material feels very sturdy. Easy to install and fits into the pipe securely.

Well made nice vent

Sturdy. Made of heavy duty plastic. Fit perfectly over my 4" corrugated drain pipe. The only problem is that it appears to be made for use on vertical drains i.e. sits unsecured in the drain pipe. I needed the grate for my horizontal drain. I was able to fix the problem by attaching a couple of bolts. The grate pops into place and is secured by the bolt heads in the groves of the corrugated pipe. The grate is easily removed to clear debris if necessary. Worked well following a recent heavy rain.

Looks strong and durable.Fits great.

Fits like a glove, happy

Fit right into the outlet on the buried corrugated sump.pump drain pipe

fit perfect on a 4 inch corrugated pipe. does the job. i would tape it or use a zip tie to secure it a bit more but overall good product.
