Suits straight shaft. Can be refilled with line without dismantling. Inner wall reduces the amount of dirt that can get inside the head. Lightweight and Durable. Large eyelets to enhance line life.
These are a brilliant designed whipper snipper head.
As a contractor, time is money and these heads preform beautifully and if you need more line it is only a bump away.
When the line has run out, this is when it is in a class of its own. there is no need to turn the motor off or pull the head apart to reload it, all you do is line the arrows on the head up with the outlet holes and thread another length of line through and quickly wind the head up and away you go, takes between 30 - 40 seconds from start to finish.
thankyou
