Same here. Some of mine are over 20 years old. I think Kelley was still carrying them when ML acquired them. May take a shot at seeing if they might still have any old stock in inventory.I have some that I found in a storage unit. They are old but still work great, wish I could get some more.
I’m not sure what kind of resin they were made of but they are extremely strong. They made lids and inner covers out of the same stuff. The inner covers had a tendency to warp but the lids and bottom boards worked great.never knew they made them in plastic , never rot no painting surprised there aren't more of them being made. Not sure how structurally strong they would be and how expensive but seems like a good idea
I had a few that were a little tall in that piece, and I sanded them down. Not sure why they included that. Not really necessary. Only other mod I’ve made to them is drilling 5/8” holes in the back corners for drainage.The one thing I don't like about them is the little bump up in the middle near the entrance, which makes using entrance reducers or screening them in a bit more challenging. They are beefy and will last a long, long time.
That's pretty much the consistency of them. Maybe they had them injection molded out of the same stuff. Pricey indeed though.
