If ever buying steel shelving units, either for too many books, or for a garage, I'd suggest you only get the strong steel units that you bang together with a hammer. Don't get the ones with nuts and screws....yech. There is something very satisfying about assembling something just with a hammer, and it is equally satisfying to bash them apart when moving house. Now, John...There is the shelving unit, & here is the hammer...get to it....bash bash bash. Clunk. Very satisfying indeed. With one more day before we head off due to the Big Twuck being delayed, we both just fell apart for a few hours, which was also very satisfying. Clunk. Didn't even need a hammer. So because of the delay it gives us one less day to clean up the place After we pack the stuff into the Twuck, so this afternoon I will be shovelling stones from the balcony (it was set up with artificial grass and stones etc, and it worked pretty well)...into a big bucket and taking them downstairs to the grounds...moving them around on the niftiest little trolley thing I bought for $45 from Super Cheap Auto...its a gem.
