Tuf-Tite 20" Heavy Duty Flat Lid - Septic Tank Lid - Septic Tank Cover

The 20” septic lid fits perfectly on the Tuff Tite 20” riser. Durable and inconspicuous.

It fit great, after measuring the old cracked thin Tuf-Tite lid (lasted 30 years until it got brittle and landscaper stepped on it).

I destroyed the domed cover with my mower. The 60” zero turn with a Kawasaki twin destroys all in its path. Including domed septic covers.I wanted this flat cover to replace the domed in order for it to avoid my mower’s blades of mayhem and destruction.This one seems equally well built and sturdy.My only knock is that the upper holes aren’t pre-drilled. There are 2 sets of holes, on different diameters. It was pretty easy to see the outer diameter holes lined up perfectly with my riser. Once drilled with a 5/32 bit the included screws drew the lid right down to the riser.The flush fitting lid should allow me to mow over it with impunity now and not need to trim around it.

It's low to the ground and covers it really good! Our lawn mower can go over it without any problems. Better than the dome covers.

And it fit well. We wanted a flat lid for a low profile look in our yard. The lid has screw markers on the top. It also has four pre-drilled holes around the circumference on the side. The lid secures in both ways; top and side.

Had to work with the holes a bit but worked great.

Perfect replacements for my mower damaged cover.

These lids did not fit - returned 10 lids back and have never received my refund. They have not responded.
