Window limited opening hardware?

A home owner from Sterling, VA says:

Can you tell me what the name of the item is that limits over/under sliding windows from opening too far? They are about 1.5" high, and have a small pop-out tab that, when released, prevents the windows from opening more than about 4". There is one of each side of the rear window. Do you sell these?

Thanks for posting! Have you seen our 26-362 Sash Vent Lock? Please compare it to your own hardware and let me know if you think it can be used as a replacement.

Hi, I actually stumbled across that exact part on your site after I posted here, so I ordered a few to see if they will work. They look *exactly* like what I have. Thanks VERY much!

What is the best way to go about removing one of your 26-362 Sash Vent Locks? It looks to me like you might have to destroy the lock go get it out. I have several of these that have failed. They won't stay in the stowed, or in, position.

You're correct, you'll have to break it to take it out. Most vent locks must be destroyed in order to remove them.
A handy person from Westchester, NY says:
This was my concern regarding these. They are relatively inexpensive but look effective. I'm assuming some will fail over time. Got any good ideas on how to destroy the lock (from the inside) without damaging the windows when it does happen (everything breaks eventually). (when you count all the ground windows locks being replaced, I'm up towards 30 locks. So just playing the odds).

Sure! I slide a putty knife under the lip of the vent lock and force it out from sash.
