Question about Gardena RollUp

The new hose box does not fit into the old holder. It can be temporarily hooked in, but the new system is different.

I also found this overview of the dimensions of all Gardena RollUp wall-mounted hose boxes useful:

The wall brackets of the roll-up wall-mounted hose boxes M/L, L and XL now have 3 holes for screw fastening. The hole pattern of the two upper screws corresponds to the roll-up automatic wall-mounted hose boxes 25 and 35 (up to year of manufacture 2020). Only the 3rd middle, lower hole must be re-drilled.

I can't say because I don't know the old bracket. To be on the safe side, I would contact the manufacturer.
