Slider bolt

Thanks for posting. It's impossible to say for sure what slide bolts you might need with just this information. Replacement slide bolts must be very close to the original in design and shape in order to work. The 91-140, for instance, is a pair we often see in storm doors, but this is just a blind guess. We have no way of knowing for sure if this is what you need. Take a look and see what you think. If in doubt, send us photos of your old slide bolts removed from the window, and we'd be happy to see if we can find a better match.
