Replacement photogate fences for the Smart Timer (ME-8930).
Product Summary
The ME-8933 Picket Fences (set of two) are the same ones included in the ME-8930 Smart Timer and can be considered a replacement part for that product. They may also be attached to a GOcar to monitor its motion, especially with the Inclined Plane Accessory (ME-6965) for the PAStrack.
