Best kennel door dog or box latch made in Texas, hope this helps somebody

Here is the spring loaded latch they sell down here where I live at the feed stores, this was designed by a vet who worked on cow and hog dogs and owned his own ranch, very nice guy who patented these, I see the crummy stuff on sale at the lumber yards and at TS etc tsc, only thing is they are not lockable but they can be slamed shut with the ramp and my mule has never figured out how to get out of his pen after i instaled one, there kinda high but are not going to be opened by a dog or horse, they are in about every auction barnon US 59 withmetal gates and i put them in several sets of pens i built and tractor doors and tool boxes etc, help this helps somebody keep there dogs locked in better than the junk stuff out there made in chinka!!lol
