Very solid and inexpensive poly lid
359083
The one hole that is pre-drilled on this lid is about 2" in diameter, which does not allow for a rubber grommet to totally seal an exit pipe unless there is a 1.5 inch pipe grommet that would fit this hole; sewage exit lines are normally 2" or wider.  However, this hole size is perfect for an AK Industries sump-pump power cord grommet, and there are two reinforced hole areas where a 3" hole can be drilled with a key hole bit and mandrel ($25 on Amazon) that will allow a 2" pvc pipe to exit and be able to put a rubber grommet (AK or other) on the pipe to totally seal the hole.  If you have a two pipe set-up like I do, one is a 2" vent line and the other the 2" exit line, then you end up drilling another hole with the 3" key hole bit; clean poly strands around cut hole for smoothness.

Not sure if this lid is perfectly flat when put on the floor but will find out when I go to install it.  An installation kit of washer and screws from AK Industries is pretty heavy-duty, so you are going to put about 5/16" holes in the lid lip to fasten this lid down which has about a 1/2 inch outer rim on it.  Have fun.  Put foam tape around edge of lid where it fits into basin top; this lid is about 1/4 to 3/16 less in diameter than a true 20.5 inch poly lid.

I have bought several of these to use for holiday lighting connections and even to weatherproof some home-made lighting controllers.  They are not as heavy-duty as I expected, but they are solid-enough to hold-up in most applications, and for the price a really good deal.  Previously I was using tupperware type containers, but these are much better - they have built-in ports for the wires and easy snap lock closure.  They are not waterproof, but work fine to protect the contents from even a driving rain.  Highly recommend.

These lids work better than I expected, given that the material isn't the thickest feeling plastic I've come across.  It forms a tight seal with the tervis tumbler, although I haven't tried inverting the tumbler/lid combo yet.  The sliding cover for the opening became a little slack after a few uses, but hasn't inconvenienced me yet.

I purchased this Gray Rubbermaid Commercial FG9S3100GRAY Brute Tote with Lid, 20-Gallon Capacity, on a whim.  I have several of the other Rubbermaid storage containers and this product is much more rigid and, to me, far superior to the more rubbery plastic of the older containers I own.  This container should last much longer, with the abuse I give them, I am sure.  I will use it for storage of components that I use in my electronics hobby, specifically the Solar, battery chargers, LED light strings projects, Led modules and control transformers I use.  The rigid build of this molded container becomes obviously better, when you go to snap the lid on and it stays put.  I won't use any other storage bin, I know of now, but this one.  One project I am planning is a planter for aeroponics use.  I plan to use one of these and a liquid storage and fill container, pump and misters.  I'll first attempt to make up solutions as needed for growth and flowering thru fruit.  This container is perfect price and quality of product.

I bought this lid for my husband's Yeti Rambler (30 oz). He loves the cup, but wanted to have a lid that closed since my toddler has knocked it over several times. I thought this would be perfect for what he wanted!

Pros:
*It fits the Yeti Rambler perfectly.
*It has a rubber seal that fits tightly.
*Made from a sturdy, high quality plastic.
*BPA free.
*We no longer have to worry about major spills.
*Keeps drinks cold or hot longer!
*There is a little circular indent in the opening that holds a straw in place.
*Fits all 30 oz. tumblers.

Cons:
*The lid is NOT spill proof. If you knock the cup over, the liquid will slowly leak out, but it's much better than the original lid.

Overall, I'm pleased with this lid and I'm glad I don't have to worry about my toddler spilling my husband's drinks! 5 stars!

I received this product at a discount in exchange for my honest and unbiased review. All opinions are my own and I will update my review if my opinion of the product changes.

Great sturdy lid.  Fits perfect for 8 inch across pots and pans.  I can't imagine a more expensive 30 dollar lid being that much better.

Don't bother with the super fancy brands.  I looked a bunch of compost bins including the simple human ones but this one had the tightest fitting lid.  Solid all around.

This is a very sturdy mono that works well with my heavy beast 400mm lens and DSLR. It's half the weight of aluminum equivalents and fits in my smallest suitcase. Additional mounting plates are inexpensive.

The pictures of this item, here on Amazon, are a fair representation.  This container is made of precisely cut glass segments with tightly fitted brass channel wrapped around all sides of each glass piece.  The well made segments are soldered together at the vertices where the pieces meet.  The soldering is quite neatly done.  Joined, as described, at the vertices, the box is not sealed - not air or liquid "tight".  My unit had no scratched glass, the brass trim was meticulously done, and the result is about as solid as such a thing could be.  I'm very satisfied, and the container will protect the fragile painted Japanese egg which it now contains, while not too adversely affecting the display, because the container has its own interesting appearance.

Great price for protecting your equipment. The foam insert keeps contents intact with no movement of equipment. The plastice shell coud be a bit more rigid but for the price, its a non issue...simply manually align lid with bottom and snap the 4 fastener in place. When closed, it remains closed securely. If want a truly rigid case, youll have to pay way much more. Besides, other plastic cases that cost more still require same process of alignment for securing contents.

The shell's lines add appealling aesthetics but actually contribute the case's rigidity. Time will tell what the fasteners can actually endure, but on the surface, they look and feel as though they will hold up.

Pros: sturdy, not too tall, easy to use plastic lid that tightens/loosens well, good seal. Heavy glass.
Cons: Even with careful pouring a drop or two trickles down the front. Not tempered so can't take any warm or hot liquids.
This is not a major concern, and I really like these for storing water.

So far, so good! The lids work well for appropriately-sized, round containers.

This a great enclosure for the price and ideal for microprocessor projects with visual data displays because the transparent top cover allows you to mount everything inside the box without having to do cutouts for the display. For those reviewers complaining that this enclosure is not watertight, any moron can tell just by looking at it that it's only "water resistant". What to you expect for such a low price?

These fit the hinges perfectly but you will have to get some small sheet metal screws to lock the hinge pin into place. Bear in mind that the vent lid is actually a generic lid with a metal hinge riveted on to match the fixed hinge on the trailer. The contour of the vent doesn't exactly match the seal on the fixed part of the vent so some air could still enter at the corners. I don't see this as a problem since the vent edges turn down enough to prevent any water from running into the vent. These polypropylene vent lids are a lot cheaper than the polycarbonate, I hope they last. I am not sure what material the old ones were made of but were probably original on my 1988 trailer. They were cracked and disintegrated when I dropped them on the ground. I am happy with the Camco replacement lids that I purchased and would recommend them to anyone needing replacements who doesn't want to spend an arm and a leg for the polycarbonate ones. I took a star off for not providing the little sheet metal screws to retain the hinge pin.

I bought this for my Everest Blue 40-oz Hydro Flask.  I had debated over the one with a straw, but decided on this lid.  I am very pleased with it.  The seal is great, and there is no leakage of fluid whatsoever.  I can drink very easily, and the opening is not too wide, as I have a small mouth.  I may pick up the straw lid when I purchase my next Hydro Flask, which will be the 32-oz size.  Overall, this is a wonderful product, and I do not have to worry about leakage.  I notice some people have had problems with this lid, but so far, so good for me.  I would highly recommend this lid.

I'm very happy with these Leviton While-in-Use covers. The covers feels substantial without being heavy.  The gasket supplied is built-in and already attached to the cover and the gasket is very thick.  Even with our rough, stucco walls, the gasket appears to create a very snug fit.  Even so, we opted to apply caulk around the J-Boxes before we installed the covers.  The hinge swings easily.  I prefer the clear cover, which allows me to view the receptacle without opening the cover.  Most importantly, I am able to close the box easily with both receptacles in use.  Would definitely buy again.

BTW, there's high quality installation video for this receptacle on YouTube:  [...]
