Clear Plastic Tilt Gear for 1.5 Inch low profile READY MADE small square rod (1/8″ diameter hole)
The third picture shows the hexagon shaped tilter next to the square tilter. They are both Low Profile tilters, meaning the headrail height is 1.5 inches tall. The difference is the Tilt rod that runs throughout the the length of the inside of the headrail has different shapes. You must take the blind down off the brackets and look inside the headrail in order to determine which one you need.
Note: There are two sizes of square tilt rods for 2″ wood and faux wood blinds, one has a 1/4″ diameter, and is NOT THIS TILTER!, this tilter has a smaller square hole with a diameter of 1/8″ and is used for ready made blinds. If you need the larger diameter square tilter, your head rail will measure 2″ tall, meaning that it is high profile, not low profile or 1.5 inches tall
