Installing and leveling cabinets is typically a two man job. One man to shim and adjust and another man to level. The WINBAG® has made cabinet installation a one man job for most projects! The WINBAG® is so easy to use – slide it behind the cabinet and pump to adjust the level with ONE HAND. The WINBAG® holds up to the heaviest of cabinets as well all while being able to adjust with one hand. I can not say enough about this amazing little tool – it is easy, lightweight and you will not find any guy on my crew without a WINBAG® attached to their tool belts!
