Kastoria

I never thought I would like it until I had an application where it might come in handy...well now I use it all the time. Its great for metal fabrication for long tubing and angle iron etc. But if any of you guys have one can you please tell me if the rear leg that forms the tri pod is suppose to lock? The 2 front ones lock just fine. So if its not aligned at the right angle and you put any type of pressure on the jawhorse the rear leg slips out and crash. So just wanted to know if mine is screwed up or thats the way they all are. Thanks

UPDATE: Ok nevermind. I guess that rear leg is suppose to lock into place (found a clip on utube)...my unit is defective because after trying it, its busted. So gonna bring it back to the store and make sure the new one works before I walk out.
