## Questions & Answers

**Q: Do these blocks nest or are they solid?**
A: OX BLOX Jack Blocks are designed to stack and lock in place on top of one another.  However, they are not solid and do not nest. The underside of the blocks has heavy duty cross ribs that go the entire height of the block to increase load capacity.

**Q: Will the foursquare prongs on the aux block fit into the four holes on a yellow Camco leveling block?**
A: No!  Don't use OX BLOX with Camco Yellow blocks!  They are NOT compatible.  Only use OX BLOX with OX BLOX.

**Q: How much will it support double stack**
A: 10,000 lbs. Double stacked the max weight is the same as a single OX BLOX jack block.  I stack three OX BLOX jack blocks to support my personal trailer frame.  Of course you want to make sure you’re on stable level ground when stacking.  These blocks are super heavy duty, but they do not defy the laws of physics.

**Q: What happened to metal plate in tongue jack hole, just curious since i have 5 with it & 4 without now?**
A: Early on a small number of OX BLOX jack blocks were offered with a stainless steel plate in the post hole. However we discontinued the metal plate early on after receiving customer feedback suggesting the metal plate was not really valued.  If there is enough interest we would definitely consider offering it again as an option or add on.
