Hello Grady,

Checking with Firebug will reveal that the width of the splitbars is determined by the following CSS rules in kendo.common.css. You can either modify the file or override the width/height styles.


.k-splitter .k-ghost-splitbar-horizontal,
.k-splitter .k-splitbar-horizontal
{
    top: 0;
    width: 5px;
    border-width: 0 1px;
    background-repeat: repeat-y;
}

.k-ghost-splitbar-vertical,
.k-splitbar-vertical
{
    left: 0;
    height: 5px;
    border-width: 1px 0;
    background-repeat: repeat-x;
}
