Attach the Swift Leveller Flexi heads to the timber frame

Screw the head U-channel of the Swift levelling device to the frame at equal intervals, then repeat this around the whole frame.

Move the frame and drill the centre holes in the ground

Move the frame away while leaving the templates in place, then drill the large centre holes in the ground.

4
