Simple 12cm wide shelf which provides extra useable space in your Greenhouse. It is usually fitted at a high level (e.g. around eye level) and is useful for putting odds and ends on such as thermometer, plant labels, string etc. This shelf adds strength to the Greenhouse frame as it joins all the glazing bars together. It is designed to go the full length of the side or the full length of the gable in the Greenhouse. The length shown is not the actual length of the shelf but the length of the Janssen Greenhouse side or gable it will fit into, the shelf is a little shorter. This product is in 'Mill Finish' meaning bare aluminium which will discolour over time, a powder coated version is available at extra cost that will stay looking nicer for longer.
