Good value, holds circuitry and stays dry

This underground splice box offers good value. Applying rubber butyl tape and screwing it down makes it waterproof. It holds a large amount of circuitry while remaining dry, even when buried in the ground. A whole processing computer fits inside and performs well. Monitor temperatures for sensitive components.

Pros
  • + good value
  • + waterproof with rubber butyl tape
  • + holds a lot of circuitry
  • + remains dry when buried
  • + fits a whole processing computer
Cons
  • − requires temperature monitoring for sensitive items

Sturdy box, but inspect it on arrival

This box is sturdy and gets the job done, but it should be inspected closely as soon as it arrives. The unit received had a broken corner. Because it was needed right away, caulking was used to seal the damaged area back together rather than returning it. The box itself is solid, but buyers should check for shipping damage before use.

Pros
  • + sturdy construction
Cons
  • − arrived with a broken corner

Strong Lid, No Seal, Side Walls Flex

The lid is strong and fits well, though there is no seal, so caulk sealant was used. The side walls flex inward when backfilling around the box. It works as a sump for a sump pump with an added riser and suited the intended application.

Pros
  • + strong lid
  • + good lid fit
  • + suitable for intended application
Cons
  • − no lid seal
  • − side walls flex during backfilling

Sturdy Access Box for Sewer Cleanout

This underground splice box is sturdy and has held up to being stepped on for over a year. The lid stays in place and works as intended. The bottom was cut off so the box could slide over a sewer line at the cleanout location, and it fit well. It is a solid option for accessing a basement floor sewer cleanout.

Pros
  • + sturdy construction
  • + lid stays in place
  • + withstands being stepped on
  • + good fit after modification
