Guide wheels ensure sharp clean lines when trimming around ceilings, baseboards, windows, doors and moldings.Our products have improved the design structure of the guide wheel to ensure that it will not fall off during use. The rotatable handle design, also known as universal rotator, can be adjusted from left to right, up and down, or at any angle. It is very convenient to use.Before using, please take care to lock the handle tightly to avoid the rotation of the handle affecting the application. The paint edge trimmer has 5 mm long, dense and flat bristles with high paint absorption capacity, resulting in a smooth film. It is a widely used edge painting tool. It can be used manually or with an extension rod with threaded connectors on it. It is worth noting that after connecting the extension pole, you need to tighten the knob on the handle to prevent the handle from loosening and affecting the correct direction of painting. Warm Tip: When painting the corner of a wall, if both sides of the wall need to be painted with the same paint, you can confidently cut into the corner of the wall for painting.If the other wall does not need to be painted, it is recommended to use it together with protective tape for better results, considering that everyone's experience is different. The paint edger has a thicker shell, a fuller glossy color, very fine detailing with no protrusions, and a very smooth guiding wheel rotation. It's a good paint edger tool or walls and ceilings.
