    • Paint roller grid includes a pair of hooks each including a rearwardly extending upper portion and a downwardly extending inturned lip having a forwardly facing inwardly angled surface for engaging an outer cylindrical surface of a container below the container rim when the hooks are hooked over the container rim and the grid is inserted into the top opening of the container. The hooks may be spaced from a bottom edge of the grid a distance slightly greater than the height of the container, whereby when the grid is inserted into the container opening and the hooks are hooked over the container rim, the bottom edge of the grid will engage the inside bottom surface of the container. A pair of feet may extend rearwardly from the grid for engagement with the inner cylindrical surface of the container to prevent the grid from moving within the container during rolling of a roller cover on the grid wiping surface.
    • 油漆滚筒网格包括一对钩,每个钩包括向后延伸的上部部分和向下延伸的内侧唇缘,其具有朝前的向内成角度的表面,用于当钩钩在容器边缘上方时接合容器边缘下方的容器的外圆柱形表面 并且格栅被插入容器的顶部开口中。 钩子可以与网格的底部边缘间隔开一个略大于容器高度的距离,由此当格栅插入容器开口中并且钩被钩在容器边缘上时,网格的底部边缘将 接合容器的内底面。 一对脚可以从网格向后延伸以与容器的内圆柱形表面接合,以防止在滚子盖在网格擦拭表面上滚动时格栅在容器内移动。
