Review: Great product, well made, good quality. Would EASILY buy again. - This thing is GREAT! It worked far better than I anticipated. I used it to house a splice in my low volrage outdoor landscaping lighting. The splice has 2 lights coming off of it. So this housing has 4 cables runnng into it. Note that this comes with a screw terminal to connect wires, but this was not usable for my application. Instead I used 2 gigantic wire nuts. I love the included rubber gromits in 2 or 3 sizes. The lid seems to seal well. One modification I did make was to screw a steel landscaping edging spike onto this, so I can stick it into the ground and keep it from sliding around, while keeping it off the dirt. This item seems durable and likely to hold up in the weather and heat. I would easily buy this again.
Review: Nice heavy duty sealed box! - I ended up returning this item. It was too small for what I needed. Yet, I gave it a 5 star rating because it was still a strong box and very durable and useful for those who need this size.

### ⭐⭐⭐⭐ Works alright for the price
*by A***Y on May 17, 2026*

So far so good. Decent quality and good sealing fit. The connector strip leave a little to be desired, but had my own to use. It was a little smaller than expected, but I think that is my fault as I may have read dimensions incorrectly. Still works for my application so 4 stars, would be 5 if the connector strip was a little better quality.
