We have been experimenting with alternative anchor designs to try and come up with a more secure way to hold the anchors in place. Although we cannot change the staafje, we can replace the way the O-ring connects to the timber frameset.
One method is to use a spiralled hook which we refer to as a 'piglet-tail hook'. This lets the O-ring be connected without it requiring the drill. On the other hand, the extra loop still prevents the O-ring from coming loose in the event of extreme wind buffetting.
