Residential & Commercial Security - Locks, Keys & Dead Bolts - Looking for a handle/lock for a shed

I saw a nice door handle with lock on a sample shed in HD. There is a T-handle on the outside and in the inside, attached to it, there is kind of a half-cirlce made of metal, and when you turn the T-handle you lock the door by sliding the half-circle behind the adjacent door.
This lock aparently comes with the sheds that you buy from ShedsUSA through HD, but all I am looking for is the lock itself. I searched all over the web with no luck.
Does any one know what I am talking about...?

I would think your best bet for an exact match would probably be to contact the company/supplier-hopefully they would sell replacement locks you could purchase individually. If HD is no help, try the manufacturer itself.

T-handles themselves are readily available from many sources, the cams/accessories for a particular application can be more difficult to find. Perhaps someone else will have experience with this particular lock or have some other ideas for you.

Thanks, I'll try that.
