In winter easily removable telescopic supports can be placed under the arches of the greenhouse. This will give the greenhouse additional strength and increase the maximum snow load. During the summer period the telescopic supports are dismantled.

The universal reinforcement is a square tube with a crossshaped tip on the top and a footshaped tip on the bottom. A cruciform gable supports the arch of the greenhouse. The support is adjustable: 2.1m to 2.18m
