Note Regarding Vinyl Patio Inserts:
"Vinyl" Inserts are a newer offering in Sliding glass door pet inserts. Another description of these inserts is "Plastic". They are typically thicker than aluminum inserts, and require the customer to permanently install them with hardware and screws. Most aluminum inserts can be used in a permanent or semi-permanent installation making them more popular and friendly for pet owners.
Having either vinyl, wood or aluminum sliding doors does not mean you need the same type of pet insert. Aluminum inserts are the most popular choices for all sliding door customers.
