i want to order some patio doors for a client and need specs, possibilities..how do i do this?

Hi Jerry,
Have a browse some of the patio door products listed on Modlar: https://www.modlar.com/products/doors/patio-doors - then get in touch with one or a few of the brands that make those products, who will be able to get you all the information you need. Each product also has a URL that links directly to the brand's website so you can easily find their contact details.
