This tilt mechanism is used in Bali and Graber's 1" mini blinds that have a cordless operation. 

It fits into a headrail that measures 1 1/2" high by 2 1/8" deep. It accommodates a 1/4" tilt rod with a single rounded notch cut out of it. 

This set includes one white plastic tilt mechanism, one clear plastic stem, one clear plastic wand cap/sleeve, and one metal hook.

To replace, first seat the white piece inside the headrail. Then, snap the stem into it from the outside of the headrail. Once the stem is firmly inserted, it is not removable. 

Sold individually.
