The Vision Industries Patio Door Handle fits most mortise-style latch systems. The movable lever pin accommodates both center and side hole fabrications. The outside pull and inner baseplate are solid zinc with a durable powder coat finish. The inside pull is wood with a natural grain finish. This is made by the same company that provides the hardware attached to the most popular brand patio doors sold at Home Depot, Lowe's and many other window and door outlets.
