The same as we have on the Simmons hood fitted to the Jas. polished stainless with the sealing rubber for after the material is fitted.
They need an over centre catch for then ends and will go onto manx clamps with a spacer under the hood hook or I have the correct width stainless box section which will come with it.
These work even if the screen is fitted with the hood slot to the rear.
There is also stainless U section that needs final tweaking to fit so clip on doors are a possibility if the screen is the correct way around. £300 the cost price for top rail, rubber seals, 2 door rails and a length of box for hooks.
Can post but collection preferred from Evesham so system can be seen on our buggy
