Coverstar Stop Block/Slider for 403 Series Top Guide System and Wheel Assembly, M9670

The Coverstar M9670 is the stop block and slider for the 403 Series top guide system and wheel assembly. It is the genuine Coverstar part.

What it does

An automatic cover runs its leading edge along a guide track on each side of the pool. The stop block sets where that travel ends and the slider is the surface the wheel assembly rides against. Both take the load every time the cover opens and closes, which makes them the pieces that wear out first while the track itself stays serviceable.

Before you order

Coverstar lists this part for the 403 Series top guide system, so check which guide system your cover uses. Since the system runs a track on each side of the pool, look at the opposite side at the same time and replace both if they have aged together.
