Small-diameter circular bubble level for checking RV and trailer levelness. 360° visibility allows reading from any direction. Place on any flat interior surface. Recommended by BAL for use during jack leveling procedures.
The BAL 25025 is a simple circular surface bubble level — the compact tool BAL specifically recommends in their leveling guide for checking trailer levelness during the jack adjustment process. Its 360° visibility means the bubble can be read from any angle without repositioning the level, and its 1-3/4" diameter is compact enough to keep on a countertop or tabletop permanently without being in the way.
To use, place the level on any flat horizontal interior surface — a kitchen counter, table, or stovetop cover — and adjust jacks until the bubble centers. BAL's leveling guide notes that whichever direction the bubble is offset indicates which side of the trailer needs to be raised.
