Stack nicely for storage and are very sturdy for the trailer jacks. Love that they are made from recycled materials and mad in the USA.

Ox Blox Rox!

Nothing better. Stacked and screwed 2x4's are junk. Ox Blox are awesome. Thanks.

Perfect!

Have been using treated 2x12 and stacking when needed. Wow these blocks are awesome! I get a lot of comments about them and I recommend them to everyone I talk to who has a trailer. Totally worth the price! I bought 2 and it’s plenty of height!
