The Winbag is an inflatable assembly cushion and a versatile tool on construction sites or in the workshop. It replaces wedges and wooden blocks when installing windows, doors, furniture, or appliances. Simply pumping the Winbag allows you to adjust, lift, or align it with millimeter precision – without jamming. With its high load-bearing capacity and precise adjustment, it saves time, protects materials, and ensures precise results – even on delicate surfaces.
