The Post & base collar attaches firmly to the post by simply sliding over the top and seating into position. It provides a strong platform for attaching the Skipper recycle bins, safety dispensers and sanitiser brackets; turning the Skipper post & base system into a fully equipped, free-standing safety & recycling station.After the collar is attached, the Skipper unit can snap-fit to the post as usual, providing a unique combination of a 9m (30ft) barrier and recycling point. A sign holder can also be attached to either the Skipper unit or the post & base cap to display your messages.
