Is there a hinge that locks into the 90 degree position?

Question

I need a hinge that starts off at a 0 degree angle and when you open it to a 90 degree angle (L), it locks into that angle, and you have to manually change it back to a 0 degree angle. Is there a hinge like that?

If these are not what you are looking for I would check out the site and see if they have what you want.

Answer 3

The type of hinge you are looking for is often called a 'table', or 'shelf' hinge.  You might also consider a 'table leg' hinge.

You didn't specify size requirement, or limitation, so here are a few for your consideration.

This is a link to several 'table', 'table leg' and 'shelf' hinges -

And this link is to one Ive used in making very heavy duty restaurant style tables -

"Drop leaf" hinges are often 'just' the hinge, and the support mechanism is seperate.  The support can be either a slide out style, or hinged mechanism, but it is almost always seperate from the drop leaf hinge itself.  These hinges and supports can be found at most wood working suppliers like Rockler, and Woodworkers Supply.
