Storm door lock mortise lock set for Pella

Question

Were there any other versions of this lock back in 2010 when this door was purchased.  I don't remember exactly how it looks and don't have the dimensions but it has the two point lock and a lower key as shown, I just don't remember if it had two square handle mechanisms and lock holes for universal left and right...let me know

Thanks for writing in. It's a bit difficult to say what Pella lock you need exactly without seeing the original. Two locks commonly used for Pella storm doors are our 40-191, and also the 40-198. Look over both and see if one is a good match for your sliding door's old mounting holes and the cavity that accepts the lock. If you're uncertain, let us see pictures of this cavity as well as dimensions. Many thanks.
