What's in the kit
An assortment of TPU shims in a spread of sizes — enough to fit any manhole cover, because nobody ever standardized the gap under one.
No calipers, no math, no trip to the hardware store. Start with the biggest shim that goes in, work down until the cover sits tight, trim the leftovers. One kit, one cover, one less noise in your life.
FAQ
Is this legal to install?
Covers on your own property: driveways, HOA grates, private vaults, warehouse yards. Public street manholes belong to the city — call them first, and let us know if they ever call back. If you are out of patience or aren't scared of the man, proceed with caution.
Will it fit my cover?
Cover gaps are gloriously non-standard, so the kit ships an assortment of sizes to fit any manhole cover. Don't measure anything: start with the biggest shim that goes in and work down until it's snug. One kit handles one standard cover.
What tools do I need?
Something to lift the cover (pry bar or hook) and something to trim with (scissors or a utility knife). That's the whole toolbox. No ruler required.
How long does it last outdoors?
TPU is flexible engineering rubber — weather-proof, UV-resistant, and happy to stay squashed under a hundred pounds of iron without splitting.
