Hi.

   You are purchasing one chainsaw tensioner/ adjuster set .

This is an aftermarket product that will suit various sized Chinese manufactured chainsaws.

Ozito 37.2cc, chainsaw size  45CC 52CC 58CC and various other models.

It has three parts as you can see in the pictures.

A main shaft, adjuster pin and adjuster screw.

Please ensure you check the parts are a  match with what you require.

Dimensions are in photos.

Quality replacement parts.

I have personally used the part myself so I can vouch for it.

Please message me if you have any questions or requests.

Cheers
